### WebAssembly

TODO
WebAssembly was considered as an alternative to CEL, up to having a [proof-of-concept implementation](https://github.com/jpbetz/omni-webhook/blob/main/validators/wasm.go).
However, all current WebAssembly runtimes require `cgo` to build, something that
might be difficult to integrate into api-server. Additionally, passing strings across
a WebAssembly boundary is currently dependent on the target language, so any supported
target language would need a small shim library to be supported.
