    These jobs can likely use reduced runner sizes to avoid wasting our CPU quota, as much of the long-running part of the job is single-threaded.

    This will also give us more (job) parallelisem from the same number of CPU that we are using.

    PR reduces select container sizes / cirrus runners. Not using unnecessary “large” runners is a good idea.

    • code review ✅
    • All (relevant) CI builds run ✅

    Looks good to me, makes sense to me to use smaller runners. All the checks passed on this PR and the longest running one only too 44 minutes

    is there any reason to keep CentOS, depends, gui and MSan, depends on a lg runner?
