I read recently that Ubuntu officially supports certain Raspberry Pi hardware on the desktop as of version 20.10. See the announcement here: https://ubuntu.com/blog/ubuntu-20-10-on-raspberry-pi-delivers-the-full-linux-desktop-and-micro-clouds

I'm wondering if that official support extends to other flavors such as Ubuntu MATE, Lubuntu, etc?

I know that Ubuntu MATE has made images available for Raspberry Pi for a little while, but I was under the impression that was due to extra development done by the Ubuntu MATE team, and it was not "officially" supported by Canonical.

My guess is that the work done by Canonical will benefit many of the other flavors as well, but I was hoping someone here could confirm.

Thanks for any insight you can provide!
