Hi Russell Neither refpolicy nor policycoreutils are in the list of key packages. In the upcoming hard freeze, for non-key packages with (non-trivial) autopkgtests, the rules of the soft freeze still apply [1].
So you could avoid the need for unblocks for these packages by adding an autopkgtest that tests the as-installed packages in a new upload. Regards Graham [1] https://release.debian.org/bullseye/freeze_policy.html#hard
