Fair enough, but you're not asking for support and neither are the
Fedora and CentOS package maintainers. If the official docs say
something is not supported (N.B. it's not a recommendation, it says
unsupported) then don't do it and then ask for support. Doing so
indicates a failure to read the docs, so a reasonable response is
RTFM.
