Yes.

I can't find any reference to the schema change you're referring to
(although it might be related to the other protocol bump), that would be
considered verboten under the current approach.  I've been present during
numerous discussions where a change to -fixes was put on hold because it
changed the DB schema-- this is for good reason:  The one time it happened,
you had same-versioned myth machines which were incompatible with one
another.  Even worse, you had .20-fixes machines which were incompatible
with one another!  This is A Bad Thing (tm).  It's considered completely
forbidden now.
