If you go back in history, RISC was Reduced INSTRUCTION SET computers, not Reduced ADDRESSING MODES computers. RISC was more than reduced number of instructions: There was a reduction in number of instruction formats: All instructions being x bits wide, all having the operand spec in the same bits etc. The regularity was just as important as the count. It lead to far more direct hardware decoding of the instruction / operand codes into signal lines within the CPU, avoiding (possibly multiple layers of) microcode decoding, making faster instruction execution possible.
I see that more in microcontrollers where instruction memory needed not be organized in bytes and any number of bits could be realized as instruction word size. This way the processors only had to fetch one instruction word of n bits instead of several bytes and could execute most instructions in a single cycle.

Did you ever see a 8 bit RISC CPU (as opposed to microcontroller)? I still like to program on the granddaddy of all RISC (and CMOS) CPUs and I can assure you that the addressing modes are extremely reduced there. Some people went so far to call it one of the earliest and most radical RISC implementations ever. I think this spartan design was not due to a radical design philosohy. It was probably the low number of gates available on the die because it was also an early CMOS design and CMOS gates need transistor pairs.
I have lived with several Zen masters - all of them were cats.

His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.
