MariaDB Plans - Replication

We are discussing points for the replication part of the MariaDB roadmap.
So far discussed:
Replication filters, like --replicate-do-db and friends, need to be possible to change dynamically, without having to restart the server. Having to stop the slave should ideally also not be needed, but is less of a problem.(complete) Transactional storage of slave state, rather than file-based master.info and relay-log.info . So the slave can recover consistently after a crash.(complete) Global transaction ID, so the slave state becomes recoverable, and facilitate automatic moving a slave to a new master across multi-level hierarchies.(complete) Support in global transaction ID for master_pos_wait()(complete)
- Hooks around rotation of the binlog, so user can configure shell commands when a new log is started and when it is ended. The command must be run asynchroneously, and get the old and new log file name as arguments.
- Sending of heartbeats from master to slaves, so slaves starting up can know in finite time where the master is.
