Resolve considers timelines to be just that, timelines, or reels of timelines for large projects. Making a timeline per scene is not practical in Resolve and so compound clips are often used to manage scenes.
Breaking up a show into scenes is a pretty common approach. "You work on this scene and I work on that one." And the only way to do that easily is to use a different timeline per scene. Editors do this a lot.
Not only does it make it easier from a breaking up the work perspective, but it keeps my scene from screwing up anything later (or earlier) in the cut. With the reality of today's timeline where there are multiple video tracks and an insane amount of audio tracks, the risk of screwing up something down stream is very high.
And each of those timelines are going to have different versions. Quickly you wind up with a lot of timelines, with some combination that you want to string together.
Editors are now frequently required to have temporary foley, nat sound, music, sfx all mixed at even *7.1* plus vfx, speed changes, split edits which all add to the track count. Media Composer's sync locks does a pretty good job of keeping things from getting out of hand, but even then one scene per timeline is frequently done. And with no comparable sync lock feature, it can at times be *very* uncomfortable working in one timeline in Resolve.
So nested timelines, IMHO, should be improved upon in Resolve. For example, their waveforms should show on the Fairlight Page. And there should be a way to ripple through to the master timeline changes made in the nested timeline including automatically expanding or contracting the length of the nested timeline in the master timeline. For example, if I edit timeline_1 which adds 40 seconds to it, there should away to update timeline_master so those 40 seconds are ripple-added to timeline_master.
I know you guys have a lot of work to do.

One of the things that's been hurting Media Composer for a years now is Premiere's tabbed timeline display. Not the same as rippling like I mentioned above, but it does point to the fact that multiple timelines has become very accepted.
Anyway, good luck with all of this.
