The puppet source package, recently recently dropped the puppet-common binary package. This package has been a transitional dummy package since stretch.
Unfortunately there are still a substantial number of packages depending on it. They are listed by maintainer at the end of this mail (the list is based on packages that currently have the issue in bullseye). I filed bugs for the first couple I spotted, but then started to wonder if, given that nearly all of the packages involved are maintained by the openstack team, a more centralised approach is better. If I get no response however I will go ahead with a mass bug filing so the testing autoremoval system can do it's thing.
