I'm looking for the same. It seems that a possible implementation may be wrapping a WASM Runtime inside ProxyHttp trait and forward events to WASM modules. Unfortunately there is no TCK (yet) to probe that a proxy-wasm implementation works as expected.

This something the ISRG River project will work on. See https://www.memorysafety.org/blog/introducing-river/.

A blocker for proxy-wasm support is body modification not being allowed.

It looks like the blocker issue with body modification is already solved Do you have any plans to implement proxy-wasm in the near time?
