What? I'm not talking about anything like that.
Proper shared libraries aren't a problem in any case. We already have a
perfectly adequate policy for that. By policy, so far as actual shared
libraries are concerned, mysql-libs and mariadb-libs would have the
exact same provides, if they were in fact providing ABI/API-compatible
libraries, and would not have the same provides if they weren't.

You are assuming that mysql and mariadb's libraries will be API/ABI
incompatible. I don't know if that's true or if it isn't, but in either
case it's pretty irrelevant, because library provides are already
specifically covered by a perfectly adequate policy.
