> Smart background replace with optional green screen support

I find that one curious. Can you elaborate on it? I'm having trouble thinking of a situation that would make it a need. I don't particularly want people having a view into my home, but it's easy enough for me to sit in front of a wall/curtain, or just move personal objects out of view.

The others are more interesting; thanks for the list.

Allow me to add one relevant to certain communities: Audio suitable for musical collaboration. The music teachers, students, and performers I know prefer Zoom because it works better than the alternatives they have tried. I think it's a combination of tolerable latency and the ability to disable audio processing that's designed for speech but distorts live music.
