(like using RISC internally and translating the instructions it)
Hrm, doesn't that mean that RISC won out in the end, even though the
companies that first introduced it didn't? So from the standpoint of a product manager deciding whether to fund a RISC project or a CISC project, the right thing to do was to listen to the debates.
All that matters is the real-world performance.
To the end-user, and to the blockchain, of course!
But if you're the company that has money to spend and are trying to figure out which design to spend money on, you want something like the η-factor. Just like how the project managers at Intel listened carefully to the RISC-CISC debate and made the right decision in the end even though, at the time they made that decision, RISC chips were overpriced and performing poorly.
