Thanks for the feedback, I’ll look at that commit and make the suggested changes. Also: oops I meant this to go to cfe-commits, not cfe-dev. I’ll move the discussion there when I update this patch.

That commit makes the flag significant when modules are enabled and rejects a PCH that didn't enable the flag.
