I've added some things, that I think are essential. I think we should track assignment on the existing phabricator tasks list. Note there's also the bugzilla keyword "wayland" for searching over all our software.
I'm glad you're more on the fence about the EGL stream support. I switched one of my machines to nvidia after we had that lock screen bug, so I've been reading over the relevant Qt commit. It doesn't look particularly intrusive. As for the remote buffers, I'm really not happy with what happened there. It wouldn't take you long to just write a comment...
