Particularly since there's no software that used AAA. If we can do better with other things, then it's a waste of FPGA space.
Whether there is software is irrelevant, if you are going to implement functionality similar to AAA and have a choice of using AAA register formats or purposefully refusing to use AAA register formats then its cooler to use the AAA formats.
The choice then becomes what part of AAA would you implement. I think >8bit is definately what everyone wants. Then you've got the improved blitter & copper.
I understand the pro's and con's of both sides of the argument.
You could also take the actuator concept and just use a seperate video chip, with an AGA renderer into graphics ram for backward compatibility. There are alot of options for a no compromise solution.
