Canonical have never provided any resources to the wayland project. They have waited for some other distro to do the heavy lifting, you have to also remember the wayland devs have not just been working on wayland for the past 5 years.
Most of krh's time has been spent getting the mesa gbm/egl layers to a place where wayland is actually possible, and open source stack supports it.
If someone had come along a year ago with a direction for wayland and 4-5 developers there would have been very little to stop them taking the project in whatever direction they wished. You'd at least talk to the upstream project first, to see what benefit you could gain from it.
There's a pretty good chance Fedora 20/21 will see some movement in waylands direction. But if Canonical had put the effort into wayland instead of Mir we might have had a reason to help out earlier and assign resources.
