Description of problem:
While looking into OCPBUGS-1458, I've noticed this behavior:
$ for i in (seq 3)
date
oc logs -n openshift-cluster-version cluster-version-operator-7b95857ff9-dr6vd | grep -oP "Updating \K.+ due to diff" | cut -d' ' -f1 | sort | uniq -c
sleep 300
end

It does not seem to be limited to a single manifest:

Inspecting the diff (attached) logged by CVO shows that the differences are probably related to some changes in defaulting.
Version-Release number of selected component (if applicable):
4.12.0-0.nightly-2022-10-18-192348
How reproducible:
looks like always on 4.12
Steps to Reproduce:
1. Filter CVO log: grep -oP "Updating Deployment \K.+ due to diff" | cut -d' ' -f1 | sort | uniq -c
Actual results:
Many hits on various (all?) deployment manifests
Expected results:
No hits
Additional info:
Seems to be a regression in 4.12. It is possible to inspect any CI job artifacts for the symptoms, and I found no hits in any 4.11 job. Examples:
