Here's a few thoughts, and what I hope is the answer to your fundamental problem:
Use Full Clip Extents is, so far as I can see, just a shortcut to make the subclip is the same length as the original clip.
Any subclip - regardless of its original length - can be later edited by right-clicking on it in the Media Pool and choosing Edit Subclip.
Having done Edit Subclip, you could then choose Full Clip Extents if you now want it the full length of the original clip. Or you could manually enter a new start/end timecode:
I suspect the problem you're having is that you're trying to expand a subclip
on the Timeline in which you've placed it, but are running out of frames because the subclip is too short. It's not possible to use more frames on a timeline than exist in the subclip; you'd need to first edit the subclip to make it longer.
If you always want to be able to use the full range of the original clip, just click Full Clip Extents whenever you make that subclip. I personally can't see a huge benefit to having what is in effect just a duplicate of the original clip (why not just edit on the original clip?) but maybe that's helpful for setting different metadata on it or something?
If you make a subclip which is not the full length of the original clip, then later find while editing on a Timeline that your subclip is too short, you can:
1. Right-click on the clip on the Timeline and "Find In Media Pool" (or press Alt/Option-F)
2. Right-click on the subclip in the Media Pool and "Edit Subclip"
3. Adjust the Start/End timecode - or click Full Clip Extents if you want the subclip to be as long as the original clip
4. Now go back to your Timeline and you'll be able to expand the head/tail of the clip to make use of its extra available length.
Hope I understood your problem correctly and that that answers it.
(Regarding your issue not being able to make subclips at all, I answered that earlier this morning in your other post: do it from the media pool, not from the Timeline. Full details and explanatory video in the other post.)
My main use case for subclips is to create timelines by "assembling" it with subclips kind of like legos. Just grab the one you need and drag it down to the timeline.
Once there, they act like any other clip, just like they are a shortened version of the original clip without having to drop multiple copies of the original and trim them to length (and the time sink involved). However, for various reasons you may need to either expand or contract the subclip. I agree that they obviously cannot be expanded beyond the length of the original clip.
As an example, if I have a 15 minute video "take", I might have 10 30 second(ish) subclips out of that. However, when I assemble them, I might find that one in the middle of the 15 minute "take" might need a few more frames for a transition to work correctly. If I DON'T have "Use full clip extents" checked, I CANNOT expand that clip at all (or at least I couldn't when I first started using Resolve's subclips).
To be clear, once on the timeline, the subclip acts EXACTLY like if you had the original video and trim it down to the same lengths and then used the timeline tools to expand or contract the trim.
I CAN shorten the subclip without "Use full clip extents", but not extend it in the timeline. That is what I don't understand. I don't know anyone who is good enough that they won't need to adjust a cut/markers/subclip at least at some point, if not most of the time while refining their edit. Perhaps my inability to imagine it is a reflections of my limitations of an editor, but I find it hard to believe I'm alone in this.
Additionally, if I have to pull up the "Edit Subclips" screen, I can't SEE what I'm starting/ending, so I won't know if the frames are correct. That is why I use the timeline tools to do the changing of the length of the subclips.
In the example above, I am NOT trying to change the length of the subclip to past the ends of the original video it was taken from.
I really do appreciate the time you are taking regarding this feature request. However, I still feel that BMD really needs to better understand how helpful subclips are compared to markers and how markers are not a replacement for subclips (discussed in other parts of the "Subclips" series of feature requests I've made).

PS. Frankly, I'm hoping that BMD will see the utility and competitive advantage that developing subclipping and extending Resolve to have MAM features (e.g. searchable clips/subclips from all projects). In my personal case it would enable, for example, pulling all of a player's clips together in one smart bin and then going through just those to do a season highlight reel that is just uneconomical (time-wise) right now. Same for documentaries, interviews, etc. But that is a topic for another thread...
