If you carry an EGC with each circuit or grouping, they'd just .
250.4(A)(3) is the key to your thinking, Jhr. Yes, the box must be bonded, because 250.4(A)(3) says so. But 250.148's opinion on how it should be done is mute, since there are no spliced circuit conductors in the box. Just because .148 can't be applied doesn't relieve the requirement that the box must be bonded in general.
