See below. What do you think about it?

There is also https://mariadb.atlassian.net/browse/MDEV-4487 (Replication from 5.6 with enabled GTID) to be considered. It's currently Minor and has 10.0.x as a target version, both of which are questionable: recently Colin said on IRC that it should be much more than a minor FR, and yet I doubt that somebody will get to it in 10.0. Maybe it's more realistic to raise the priority but to re-target it for 10.1?
I think Monty had some ideas for doing this, IIRC it was discussed at the meeting in Barcelona in January. If what I remember is true, it is actually just that a 5.6 master refuses to replicate if the slave does not say it is configured for MySQL 5.6 GTID. The slave does not need to actually _use_ GTID. So I think Monty's plan was for the MariaDB slave to just lie to the master and say that it's a 5.6 slave with appropriate config. And the MariaDB slave would need to recognise and ignore the new MySQL 5.6 events, such as GTID. - Kristian.
