down by removing registers and/or crippling the indexing modes.

No, that would have been the Motorola 6800. The 6809 came somewhat later.

The main rivalry in the 8-bit world was between the 6502 and the Z80. 6502
fans liked to tout the fact that their fave CPU had so many instructions
that would execute in one clock cycle ... until you looked closer and
discovered that it was restricting itself to 8-bit address arithmetic,
where the Z80 was supporting full 16-bit addresses.
