Yes, this is quite unfortunate, but there are even distributions that do
not ship SELinux. And this is not a regression since 9.0.0, is it? As
we're in freeze for 9.1.0 release so reasonable bug fixes considered
safe (as in the chance for them to break more than they are fixing is
considered low) are welcome. But if, e.g., a patch (series) even though
being a bug fix contains a nontrivial refactor, it should really wait
until after the release. Unless it's fixing a critical bug.

That said, if this can reasonably be fixed without risking other issues
before the release, we can do so. But otherwise since this is a new
functionality and SELinux is not present in all distributions, there's
no reason to push something big and risky at the last moment or delay
the release because of this issue. We don't do this for AppArmor either.
