Canonical mostly did those projects to assist/enable Ubuntu Phone, in ways the wider Gnome/Opendesktop/Wayland community had little interest in supporting.

With Ubuntu Phone officially dead, Canonical literally had nothing to gain by working outside the community, and had no good arguments for why they should keep on doing their own thing in these aspects.

It must have been a tough decision to make, but I'm sure it was the right one. It was widely applauded from the rest of the Linux-community.
