That patching is nothing new. It's pretty automated on FreeBSD. It has a ports system that does just that. I don't think udev is ported though. Some linuxisms are, like dbus because several desktops need it. But FreeBSD has its own udev alternative called devd. Wayland is probably configured to just use that.
