Ah, I’ve almost always used a single monitor setup, so my use case wasn’t weird enough to break X11. That said. Even Wayland is wonky on my multi monitor setup at work, though that’s probably more a GNOME thing than a Wayland thing.
I do still think the approach they took with Wayland is a tad odd, in that everyone has to implement it themselves. But hey, if it works, it works.
