It does, but it would be hard to install MySQL in case any package 
requries mariadb, since the two packages conflict. And making the 
packages non-conflicting doesn't seem so simple -- it would mean to 
change location of the binaries or change their file-names, which would 
mean quite a lot of patching. But generally, if we find a way how to 
make the packages to be usable and non-conflicting, it could work fine.
