That's a nice idea, but...

1 - The 65C02 has the non-indexed addressing modes, which leave
a register (X) available for use. Removing these could make the
code a lot bigger. And that means even more in the limited memory
space of a 16-bit address bus.

2 - All the Apple emulators will emulate a 65C02, right?

3 - Even if you have a real Apple ][ you can still put a 'c02 in it.

4 - If someone might want to make a new device with a 6502, they
would probably use a C02.

5 - It's likely to be a pretty big effort.

Wow. That's cool. But yes, the compiler should generate assembler
or straight machine language itself.
