Ah yes, I generally agree with what you said (although I think it's fine to occasionally do destructive and weird things to your local DB and roll them back if you're working iteratively; you can either recreate from scratch if you want to make sure you didn't break anything and otherwise you might still have some pre-production stage where you would notice it if the migrations didn't work).
