The patches you see are only in a single test branch which I created for
someone who also wants to get familiarized with the build system, just like
you. This being in a branch of the official repo (not master yet though)
allows to get real builds on the CI service (which is otherwise a paid
service).

You are still very welcome to help, and I can even make you a test branch
if you want as well (or you can work on the same test branch with this
other contributor). If you come on the IRC channel (#gimp on irc.gimp.org),
you can also discuss with this new contributor (nickname "Benitoite", and
"Jehan" for me). The more people the better. This brings redundancy if ever
any of us needs to get a bit off-record for a bit (which is perfectly ok,
people have lives) so that we don't end up again in the same situation with
no package maintainer for months.
