What this tells me is that not all updates, even if they break things, will be
revertable, and for these, it's status quo with what we have today.
Allowing downgrade of updates that can be reverted would give us a little more
flexibility. We'll just have to keep in mind that not everything will be
revertable, which means we'll likely not be able to automatically rollback.

That doesn't sound too bad though, does it?
