I get that. I just work quite distantly from chips and find it interesting.

That said, licensing an instruction set seems strange. With very different internal implementations, you'd expect instructions and instruction patterns in a licensed instruction set to have pretty different performance characteristics on different chips leading to a very difficult environment to program in.

Note that this is not in any way a new development.

If you look at the incumbent ISAs, you'll find that most of the time ISA and microarchitecture were intentionally decoupled decades ago.
