> screensharing and RDP. Other implementations decided to implement those in a different way

I'm not fully up to date on the state of these things, but if the different implementations doesn't have a common interface it's goodbye to ever having screensharing work for everyone. I think that's what the parent means.

If we're lucky Discord/Zoom/etc. will implement it for the most popular compositor(s).

Similarly with screenshots - even though it's a much simpler problem it's annoying if the program taking the screenshot is fundamentally bound to a specific compositor.

If I'm not mistaken there are standardization efforts underway today though?
