Feature request: Any way to backport WASM SIMD to SSSE3?

[idontyboi]

Websites are starting to demand SSE4... sigh.
WASM SIMD requires SSE 4.1 and x64 to run on Chromium/Supermium, locking my Pentium E6500 out of this website: https://DoNoHarm.Report
It gets stuck in the loading screen, with F12 saying this:

MONO_WASM: instantiate_wasm_module() failed Error: Assert failed: This browser/engine doesn't support WASM SIMD. Please use a modern version. See also https://aka.ms/dotnet-wasm-features
    at w (dotnet.runtime.8.0.10.l8opasy4qn.js:3:1250)
    at dotnet.runtime.8.0.10.l8opasy4qn.js:3:201096

Anything that Supermium can do about this?

Always stuck on this:

There actually is a SSSE3-compatible WASM SIMD assembler, which is disabled by default. I'm not sure how it will work in practice though, but I will build it with the assembler enabled.
