I’ve written some other posts on Wayland recently, and it’s time for another one! Feel free to skip it it you aren’t interested in a discussion of Wayland and platforms. Many may …
I really don't like nate's take here. IMO it's really not that good, Wayland is still outright lacking features, even when using the craptastic xdg portals junk
I didnt even remotely imply that x11 doesn't have issues, so im not sure why that was brought up. The goal is to make wayland an acceptable and universal replacement, Everyone knows x11 is dying but wayland isnt ready to replace it yet
Things like window embedding, the wayland way is for each app to have it's own embedded compositor. Wayland has no support for things like overlays/always on top (Useful for OSKs PR has been made but like all wayland things, we might not get it for another couple years, or perhaps never), currently missing support for reading other window states (PR made for this as well, but again, who knows how long it will take), Still no support for window positioning (again PR made), Emulated input events (libei is not universally supported) And these are just the ones off the top of my head, There were others but I cant think of them ATM
Security at the expense of usability comes at the expense of security. X11 doesn't have security. Wayland doesn't have usability or security. Security is about putting walls in front of the bad guys while letting the good guys go through. Wayland just puts walls around everyone.
