i doubt MariaDb would be interface-compatible in most cases

against MySQL 5.5 without compat-packages (remi did outside
fedora-packages) as long depending packages are linked against
a specific version
Just for the record, we *did* replace 5.1 with 5.5 without any compat
package, back in Fedora 15. It seemed to go just fine; we had to
rebuild dependent packages, but that was about it (and there weren't
that many). I don't see any reason to think that replacing mysql with
mariadb would be harder than the 5.1-to-5.5 transition was.
And given Oracle's recent antics (refusal to release any information
about security patches, not including new regression tests in releases,
etc etc) we ought to be thinking very hard about doing just that.
Reality is that mysql is now open source in name only.
