Comment 9 for bug 1928508

I'm unsubscribing sts-sponsors for now, please feel free to resubscribe once this is ready for review/spsonsoring to focal.

Note that my understanding on this is that due to the added complexity of the release and then revert of glibc in focal, due to bug 1914044, any further upgrades to glibc (like this one) might have to take additional care, though I have not looked into the details of that bug.
