I assume SVE [1]/ SVE2 [2] will be implemented in future Apple Silicon processors. Possibly along with ARMv9.

Who says they don't already support SVE; is it publicly known they support it or not? Especially if the binary doesn't have to be recompiled you'd never know whether they implemented it or not right?
You can just try the instructions with an off-the-shelf assembler. They're not supported.
I’m kind of interested about what happens if you throw random opcodes at processors now!
You might be interested in sandsifter [0], which does precisely that!
