Yes this is by design. 11-STABLE contain the same drm code so no need to
use external drm-legacy. I made an attempt to make it build against 11 as
well but the kernel code has changed from 11 to 12 a lot so it wasn’t worth
it. It would require many patches for 11.

Yes, drm-legacy-kmod is meant to be used with gpu-firmware-kmod. This has
been fixed (hopefully) in drm-legacy-kmod-g20180921 but require r338807 or
newer.

I can’t test this myself so it’s not confirmed to be working yet..  Can you
try build against newer kernel and test?
