You are free to state your objections.  No one has actually pulled the
trigger yet. :-)

Yup, and that is a down side.  That's why I made it clear that this is
optional and not going to be a thing we do right away.

Yeah, I don't expect we'll actually use it for real things but it's there
if we want it.  Might be useful for piglit to keep some notes or something.

It *can* be done other ways but the fd.o admins are tired of everyone
wanting some hand-rolled solution for this that or the other thing.  With
the gitlab CI, we provide a docker image and a script and it "just works".
There is literally zero overhead for the fd.o admins to maintain the thing.

I'm really not trying to steamroller. :-(  Like I said below, we don't need
to use any of those optional features and we'll turn them off initially so
that it's not even possible to make a PR or file an issue and the wiki
won't even exist.  Once you add your key and change your push URL, you
won't even notice that it's hosted on gitlab.
