I was reviewing SPI-3 and suddenly realized that packet protocol is
restricted to DT DATA phases.  I don't remember this decision being made.
Is there a technical reason for this?

It is my belief that DT will fail in many existing backplane designs; if we
speed negotiate down to ST or SE we loose any CRC protection.  If we
convince the world to go packetized shouldn't it be available independant
of the physical layer?
