Given that RISC-I was the result of careful analysis of the requirements of compilers in the 1980s and the set of things that were possible to build with ’80s fabrocation technology, having a modern ISA that is almost identical is pretty surprising. If the problem and constraints change completely but you come up with the same solution, you might not have understood the problem.
