You wanted to ask - are there any other good reasons except possible 
compatibility  issues? :)
It would be interesting to estimate what can be broken with such change.
This breakage can be hard to catch as we don't remove mysql libs. I 
think it can arise when some program
linked to mysql library will load library linked to the replacement. If 
it just uses old mysql libraries
it should not be broken - at least, they are staying in place.

I don't know what should be preferred - MariaDB or Percona. I have 
positive experience with Percona and
I've seen that percona library can serve as a full replacement for mysql 
one. Also to note, I shouldn't make
some strange patches to Perconat to make it work (I mean asm/gcc issue -
https://github.com/OpenIndiana/oi-userland/blob/oi/hipster/components/mariadb-55/patches/cfi-issue.patch).
But MariaDB project seems to be more popular and will likely to become 
more active.
