Yes.

However, I checked the MySQL version some time ago. It is extremely similar to
our version. I believe it will be quite feasible when merging to make them
compatible, eg. just translate the event code from one to the other. Maybe we
will just merge the MySQL version for compatibility (MySQL developers do not
seem to care about compatibility themselves), and then just add backwards and
forwards compatibility translation so we work with old versions of MariaDB.

As I remember, they are essentially identical.
