Hmm, it appears I was confused as well. I started drafting this report
before discovering --add-depends, and thus the title. I guess what I
want is equivalent to #792037 but for --extra-packages instead of
--extra-repository.

I do not currently need root after packages are installed, but it is
indeed impossible to have root after build-deps (and the extra repos)
have been installed.
