> micromanaging your env
All the "micromanaging" you need to do to not have screensharing is one of the following;
1. Don't have a started dbus session
2. Don't have portals installed and setup
3. Don't have pipewire installed and setup
Meanwhile on X what you need is:
1. Have X
So no, it wouldn't work, the reason why it works for those people in the Reddit post is because they use distros and sessions that do all the things I listed that make screensharing not work if any one is not done.
PS: Wayland does have testing protocols for screenshots and screenrecording like 'wlr-screencopy' and some DMA buff one I forgot the name of. But for screen sharing there's nothing that Wayland implements itself afaik.
