Every such flag adds complexity and surface area for testing, so I'm somewhat hesitant but I'm interested to hear others' opinions on this...

I agree, we should avoid adding a new flag unless we see a real potential problem with having this always on. At this point I don't think we do. I hope to find time later today to do the final review, but have some other things to finish first so this might get pushed to beginning of next week.
