Sorry for delay with reply, a lot of MariaDB team are currently on vacation.
This also means - if you want a definite answer on this, it's better to ask 
this question again in a couple of weeks.

As far as I my understanding goes: compatibility with MySQL is not a
left-over. MariaDB is still very much compatible. 
All client binaries are compatible, for example. The number of incompatibilities 
between mysql binaries and mariadb binaries is not greater than the number of
incompatibilities between major mysql releases.  

Perhaps, it makes sense to introduce /usr/bin/mariadb as a link to /usr/bin/mysql.

I believe so (but I am not closely involved with client-side tools).
