Have you looked at the macros which creates each type of grob?  All
they do is call the same internal function (internal_make_grob), then
check validity using dynamic_cast.  Each type of grob gets the correct
properties/interfaces/class initialized from the description in
all-grob-descriptions, so I can't see why there would be any problems
later on with break processing.
