19.20-812932 release for Ubuntu

amdgpu-pro(-hwe) and amdgpu-pro-lib32 depend on amdgpu(-hwe), but actually they
should depend on amdgpu-lib(-hwe) (just like open variant packages). Because of
that even when running installer with --no-dkms, it still is in packages list
(because amdgpu(-hwe) depends on it).
Is it intentional or just a mistake?
I think this is a mistake, because if you want force dependency on amdgpu-dkms
with pro stack, you would make all other checks in amdgpu installer script. But
because user giver "--no-dkms", such checks are skipped there.

Also, I was repacking amdgpu-pro packages (ubuntu archive) to Arch Linux. Am I
correct, that amdgpu-dkms package was made with Ubuntu LTS slowness in mind,
and is absolutely unneeded for Arch Linux? Am I right that I do not loose any
functionality abilities (maybe that allows you to watch gpu's load, like
wattman) even for pro stack if I omit amdgpu-dkms?
