I think a TODO and checking flags would be a good idea, I also encountered similar things and even somehow ignoring flags fully but provide custom switches to set them.
If we touch this on a distro scale anyway, now would be a good time to ensure our distro FLAGS are indeed set for cmake stuff as we expect. Obviously there are weird things going on in some of them :p
