Thanks for the advice, I wasn't aware such an option exists. Does this
also work on the mesa gitlab or is this a GStreamer only thing?

How hard would it be to make this the default?

Yes, would be nice to know what the hotspot is, indeed.

As far as I understand, the problem is not CI itself, but the bandwidth
needed by the build artifacts, right? Would it be possible to not host
the build artifacts on the gitlab, but rather only the place where the
build actually happened? Or at least, only transfer the build artifacts
on-demand?

I'm not exactly familiar with how the system works, so sorry if this is
a silly question.
