Probably didn't even bother to diagnose the issue. It's hard to tell if it was even wayland related without logs and some digging. But lets just blindly blame wayland cause new thing bad!
Blame on Wayland is absolutely justified here. If you force changes onto others its up to you to make sure you're not breaking things.
Log in using wayland -> no desktop. Log in using x11 -> desktop. Clearly it's "wayland related" even if whatever root cause it is is something you wouldn't consider directly attributable to it. Logging into a graphical session is something that has just worked out of the box each other install on whatever random hardware I've used for many years. How is that classified as some nitpicky "new thing bad" complaint?
