You are only partially correct.

There have been a lot of mysql >= 4.x things going in recently, this
"auto-fix on start" thing is one of them (as well as the stuff in
dbcheck.cpp).

This is bad news for Fedora users, who won't be seeing a newer mysql anytime
soon.

You can't do multi-table UPDATES before mysql 4.0.4:

"Starting with MySQL 4.0.4, you can also perform UPDATE operations that
cover multiple tables:"
