The BMI? No. Dependents... well, that depends whether or not the BMI
changes (i.e. is there something line line number information or build
time encoded in it?). If dependents get rebuilt when the "meaning" of
the interface has not changed, we're probably doing something wrong.

Note that this would apply also to making "cosmetic" changes to the
interface, even if it is a separate file.
