Going through the thread I currently see two reasons to keep packaging 
mysql after switching to mariadb:

Firstly, some admins may be bound to mysql because of the certification 
or similar reason, but it probably won't be a technical reason. It'd be 
nice if admins work with providers in such cases and push them to add 
mariadb into set of "supported" options. I believe there won't be 
technical barrier to do so, so everyone could benefit from that.

Second, if mariadb differs more in the future and stops to be "drop-in" 
replacement, then we'll need an alternative for applications, where 
mariadb won't be suitable enough. Nevertheless, this is not a current 
issue right now.

In both cases we'll probably need some time to evaluate how the things 
with mariadb goes, so I'd suggest to wait, observe, test and after some 
time to re-open the discussion and make a decision about dropping mysql.

When we're talking about testing, there is a mariadb package built in 
rawhide already:
   https://koji.fedoraproject.org/koji/buildinfo?buildID=380910

We're not using obsoletes for now, so in order to install the builds you 
can do the following (after the packages will by synced into rawhide repo):

# yum shell --enablerepo=rawhide
Loaded plugins: langpacks, presto, refresh-packagekit
 > remove mysql mysql-libs ...
 > install mariadb mariadb-libs ...
 > run

Sub-package names of mariadb correspond with sub-packages of mysql.
