If they are limited to 1, then they are not appropriate to use as a deployment mechanism. Do you only have one change being worked at a time? On my team, there's typically at least have a dozen different stories being worked in parallel.

I corrected my comment, it's supposed to be "active" feature flags, so only one enabled one. Thinking is that once you've enabled one in production, it should be stable enough that you should be able to clean it up. Would still enable multiple flags existing so different features can be in progress (and locally you'd only have the one you're working on active).
