improvable, also wayland problem isn't fundamental, is the slowness to merge new protocols, wlroots, for example, add protocols that aren't approved in the wayland gitlab to make it work better, so... third option is wayland, with protocols waiting for approval(that can be updated later if the protocol changes idk)

also nvidia, but that can't be fixed with a third option anyway

to be fair people need to read the gitlab discutions, the devs there aren't approving protocol just because the sake of it, is really hard to make things work securely and on every plataform, also, there things that really don't need a protocol to work, look at the QT handoff that fixes an issue that even on xorg wasn't fixed, and without needing a new protocol

other than that, certaing things like the tearing could have being merged earlier lol
