When I introduced this rebase to Fedora, I first did a COPR rebuild of all dependent packages to find out any issues:
  https://bugzilla.redhat.com/show_bug.cgi?id=2055613
Note: some of the packages couldn't be built at all at that time, so I wasn't able to compare the build behavior before and after the rebase of the 'mariadb-connector-c' package
