> MP4 can do so much more
None of that has fallen by the wayside though? I have seen examples of all of those in the wild except for interactive menus and multiangle. Multiple video streams is incredibly rare to encounter but I have run into it a few times.
The argument in favor of flexibility (and jxl) is that if you optimize things for the "average" web user (as the essay seems to be suggesting) then fairly mundane usecases require you to start juggling formats, support becomes spotty, and things start breaking. It's nice to have generous limits within which you can be confident that things will "just work" for the end user. Even just on my own system I'd much rather use a single format rather than dealing with app x not supporting format y.
tl;dr jxl is the mp4 of image formats and that's exactly why I like it.
The only things I agree with the essay about are progressive decoding and decoding speed. Particularly the latter badly needs to be improved.

And then you go on to state that the use of said features is rare. How is that not fallen by the wayside? They features are still available and can be used. They have not be removed from the format. It's just nobody uses them. That's pretty much the very understanding of fallen by the wayside is it not?
No? If mainstream software handles the features (which mpv, vlc, and ffmpeg do) I wouldn't consider them to have fallen by the wayside.
I agreed that three were rare (two I've never personally encountered in the wild) but the rest I consider common. Actually if multiangle is referring to 3D video then I've encountered that one too. It's just that 3D videos are themselves quite rare but I think most software supports them.
