I absolutely would too if I was using 16mm glass.

For me I'm more weirded out by the two sub-4K crops being 16:9 because if you're using them for slow-mo and you upscale to 4K DCI, you have to crop the top and or bottom of the frame to fill the frame anyway. It's effectively the same shooting 2112 x 1118 and 1920 x 1016.

The thing with that is that I remember Grant Petty saying that the reason the BMCC6K isn't part of the Pocket line and doesn't have have ProRes is because they have different intention for it than the Pocket line. One of the things he mentioned was that the Pocket line can work in broadcast setups and they don't want to do that with the BMCC6K so I don't think it's to accommodate B4 shooters. I think they just figured since they were providing a Super 35 crop, they might as well offer as Super 16 crop, too, but it's just not a good fit for this camera for the reasons I mentioned.
It's also weird that the Pocket 6K doesn't have a Super 16 crop for some reason because, come to think of it, the P6K has even smaller photosights than the P4K. I think a Super 16 crop on the P6K would be something like 3330 x 1998.

Hands down. I feel like there's some things they didn't properly reconsider after deciding to drop the Pocket name for this and the PYXIS.

Well the Super 16 and anamorphic crops were added to the P4K in a firmware update so with enough demand I'm sure they'd consider adding crops but I'm sure they'd be hesitant about removing some.
Adding a 3K crop would be great though. The Super 16 crop was added to the 4K because the original Pocket had a Super 16 sized sensor so it would be cute to call the 3K crop the "4/3rds crop" since the last non-Pocket Cinema Camera had a 4/3rds sensor lol... though if it matched the P4K's sensor size, it would technically be 3186 x 1680.
