I'm not sure how big of a difference it would make honestly. The sizable majority of users aren't creators, but consumers & lurkers.

(This is backed up by my own experience here on Nostr. Any post that gets really popular, in the triple digits for likes, dozens of reposts, and big zaps, has thousands of views. Most people are lurkers, they don't comment or interact at all.)

It's a feature that a small percentage would ever use, and the effort might be better focused on making consumption better for the 99% who will be watching the videos. I wonder what percentage of users on twitch & YouTube use the built in streaming option vs something like OBS?
