(I'm not sure if your "but" is a retort, or an addendum. Assuming retort...) We can consider one more level of implementation machinery, but I fail to understand how uops aren't another form of instruction, and CPU internal gobbledygook like register files, caches, etc. aren't another form of state. It doesn't seem so fuzzy.

The difference is that you don't get to access the uops machine, subsets/sequences of that instruction set are offered as (macro-)instructions instead. Programming happens on the idea of a CPU.
