gollark: Why do people Wayland anyway? Does it offer much over X?
gollark: I have a vague idea for how I'd design a "better" protocol, but it's got a bunch of unresolved details and would likely have even fewer users.
gollark: IRCv3 could be good if anyone actually supported it.
gollark: Haven't looked much but it seems to also be convoluted and have way too many extensions.
gollark: My issues with it aren't that. I just don't think it's a good protocol/software design.
