A follow-up from #9753

is it still used?

Yes, and it is critical to keep it.

if yes, it should follow our containers policy and use ubuntu:20.04 as base

I see no issue with that. Do you want to include that in the PR? If not, please open an issue and I will take care of it.

and have some metadata as the other images do

100%
