I agree. Lots of our Rust work on low-level RISC-V cores (embedded, monitor hart, etc.) rely on RVE and they depend on RVE support on LLVM. We've waited for LLVM upstream support for an amount of years; considering how much time the community have waited for, RVE codegen can be accepted even if it's marked experimental.
