If you think about, the expanded 'big box' Classic Amiga's also fit into this bucket, when you've got an RTG card, an AHI sound card and USB controller it's not really using the original chipset for much either. Adding a PPC card is another step away from the original architecture.
I totally agree with this. In fact, I made the same argument a few months ago here on A.org when I sold off all my big box Amiga stuff. Now the only hardware Amiga I keep is a slightly enhanced A500 with hard drive sidecar using the ECS chipset for all sound and video. I made the argument that with this machine I am actually using more of the actual original Amiga hardware than I was with my decked out RTG, AHI, Accelerator carded big box Amiga. On that latter machine all tasks were done by third-party attachments, leaving the original Commodore hardware to do little else than provide power and a keyboard.
