Select yourself: either IFA_IFFLAGS or translated flags in ifa_flags.
I prefer the second way just because it is too unpleasant to add
a new attribute for sake of two bits with no visible candidates
to use remaining ones.

Perfectly!

Yes, I would prefer this... Actually, it is mostly to leave possibility
to override this bit administratively. :-) If you insist this is totally
illegal and the rule must be hardwired, new flag is really redundant.
