I was actually playing with voice rooms the other day. One can create a standing call room that people can join or leave as they see fit, without having to set up a new call each time. Discord currently has more integrations with streaming and voicechat rooms, but they had a bit of a head start, and even Element (let alone Commet & Cinny) are catching up

Element has had voice/video channels since late 2022 (though back then they only worked by enabling settings > labs > video rooms beta).

I agree with you. The good news is that it looks like some of the alternate clients are focusing on it. https://commet.chat/ has voice channels (video rooms but default to camera off), and cinny's element call support PR defaults to camera off in video rooms as well iirc.
