Because focal was rolled back (due to the d-i impact), the focal-updates version does not show the problem:
$ sudo apt install ubuntu-dev-tools pbuilder arch-test
$ pbuilder-dist jammy create
W: /home/vorlon/.pbuilderrc does not exist
I: Logging to /home/vorlon/pbuilder/jammy_result/last_operation.log
W: cgroups are not available on the host, not using them.
I: Distribution is jammy.

So this can be considered verified for focal as well.
