Maybe remove the flag so it doesn't clutter the code base? If for some reason you'll need to disable it it will be matter of one commit revert

LGTM

But I would really remove the flag - we have 16 flags set to true, and some of them are a year old. I think this is an introduction a tech debt and increasing complexity when it;s not needed
