| Wayland can't possibly replace X11, it's got a fundamentally

| Exactly, "not a Wayland problem". That's the problem with
| Wayland, nothing is a Wayland problem.

| There's a contradiction here. How do you expect to avoid
| fragmentation if adding additional protocols alongside
| Wayland is required? I mean, _obviously_ there won 't be

| there's even an XKCD on the topic.
| taway098123 wrote:
