@sbc100 did you have other thoughts on this PR? We'd ideally like to get this PR (and #208332 + #208597) landed in time for the LLVM 23 release to ensure WASIp3 is ready for LLVM 23 with wasi-sdk/Rust/etc. I think we'll probably need to backport now that the release branch has been created as well, and would you be ok helping us out with that?
