We often find ourselves blocked when a piece of content is held up in
approval or validation and we need to hotfix something or even just push
through some unrelated bit of code. I understand the desire to minimize
conflicting edits, but sites have so much content that the odds of two
libraries conflicting seem pretty slim. We'd really like to see the
publishing flow look more like a version control system and not have
hard blockers - or at least increase the limit from 1.
