I see MySQL have added an analog ours http://kb.askmonty.org/en/annotate_rows_log_event

The names of the options are different: binlog_annotate_row_events vs. binlog_rows_query_log_events

Questions (I assume you can answer them off the top of the head, if not, let's first discuss it)

- Is it true that they have re-implemented the feature after we did?

Yes.

- Do I understand correctly that the features are not compatible? (different event code)

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.

- Do these features do the same thing or one is better than the other in some respect?

As I remember, they are essentially identical. - Kristian.
