You're not actually skipping the -maint branches here, so either
you need to change this to

  except:
    - /^v.*-maint$/
    - master

which libvirt currently uses, or to drop the mention of -maint
branches from the comment.

Why is it that we want to skip those branches, anyway? I get why
they're not necessary in a MR-based workflow, but we're not quite
there yet...

Actually, now that we're using GitLab as the primary repository,
how are we ensuring commits without DCO don't slip in? We had a
hook that took care of that on libvirt.org - was something like
that introduced on GitLab?
