And to follow on from that: Shouldn't AGA be able to practically do quad-CAS in 280ns?

I'm not a hardware expert and as such I'm sure nonarkitten can give a better answer, but I always thought that the Amiga chipset internally is still 16 bits even on AGA and that's why it needs to use these kind of double modes to achieve the 32/64 bit fetches.
However, take this answer with a grain of salt until someone who knows for sure verifies it (or debunks it)
Edit: loving the all HW details in this thread by the way, helps me understand some things better
