Well, you've been able to get 528-byte sector drives for a long time. They are used inside arrays that use both PI and internal metadata. In any case Type 4 was never intended for 512-byte sectors. The existing 16-bit T10 CRC is pretty useless for 4096-byte blocks so the proposal was aimed at 4096+16 (but obviously that tidbit is outside of the T10 spec that doesn't mandate block sizes or accompanying PI types). -- Martin K.
