H, I would like to propose that any db change on a branch scheduled for release be banned. During the 4.4.0 cycle most merge conflicts occured in db related (sql) files. Also I heard several times of people having problems with testing that led to them having to wipe the db and re-init'ing it. This discipline is a workaround for commit based upgrades and helps us while we have this not in place.
