Really, by a reasonable definition CISC was dead long before x86 became a thing. We don't even conceive of architectures where every instruction has 6 operands, including double indirection and implicit increments.

Is this an exaggeration, or were there ever such ISAs?

It's a half-remembered description of VAX, but it's not much of an exaggeration if at all.

For those curious, I found this VAX manual, but haven't found anything truly egregious yet:
