That'd have to be a variably sized structure with pairs of sysreg ID/value items in it I think which would be a bit of a pain to implement but doable. The per-record header is 64 bits, we'd get maximal saving by allocating a byte for the IDs. It would be very unfortunate timing to start gating things on such a change though (I'm particularly worried about GCS here, at this point the kernel changes are blocking the entire ecosystem).
