IMO the short answer is: no.

Most opensource software that uses MySQL is riddled with MySQLisms.

Many forks exists to deal with this situation http://en.wikipedia.org/wiki/MySQL#Forks

You don't need fork for that — just enable ANSI mode.

The problem is that MySQL-based software doesn't do that and relies on the default "quirks" mode.
