I don't have all the details anymore. But one of the non obvious things for me was that foreign key cascades where not in the binlogs. I also think that some changes in the database layout could lead to strange things on the replicas.

I've been using MySQL for 23 years and have no idea what you're referring to here, sorry. But it's not like other DBs have quirk-free replication either. Postgres logical replication doesn't handle DDL at all, for example.
