Because all the builds that currently exist are defined in terms of
containers, so when you have something like

  x86-fedora-31:
    script:
      ...
    image: quay.io/libvirt/buildenv-libvirt-fedora-31:latest

you cannot just run the same job on a worker that is configured to
use the shell executor.

I guess you could drop the image element and replace it with

  tags:
    - fedora-31

but then you'd either have to duplicate the job definition, or to
only have the new one which then would not work for forks and merge
requests, so that makes it less interesting.

I don't understand what you're trying to say here at all, sorry.
