It might be very annoying but I still don't think they offer 1:1 bug compatibility, and I don't think they ever did.

CentOS stated: https://www.spinics.net/lists/centos-devel/msg19564.html

> We came up with the phrase "bug-for-bug" compatible during EL5 as a GOAL to aim for. CentOS was NEVER bug-for-bug compatible.

Rocky may have changed that line, but I would be surprised. CentOS was always "good enough".
