It's indeed nice that SVE2 binaries can run on differing HW, and fragmentation will be less because it's required in ARMv9.

> the same code will work for both the super-computer and the cheap phone. That is not possible with the x86 SIMD instructions

Actually, when the code is expressed using "portable intrinsics" (https://github.com/google/highway), the source code looks the same but compiles to SSE4/AVX2/AVX-512 and NEON,SVE,SVE2 and RISC-V V instructions.
