This way they could "help" or slow a paerticularly good or bad engine and still have their precious displacement to weight formula.
alternatively, "base weights" could be established for specific motors that replace the 1.3lbs/cc rule in those instances. this would still allow for swapping with the appropriate layout modifiers wihtout extensive rules.
they could also allow non-USDM motors to open up competition. even if only in the same family as US market offerings: toyota's later 3S series (up to the BEAMS), 20v 4AG's, etc... as most of the asian makes have sportier small engines available, just not here. the same might be true for ford/GM of europe/Australia, I'm not sure.
but they probobly wont do any of that. just like they wouldn't allow open (tto a limit) brakes as in STO/U. seems they like their rules just fine how they are, thank you.
