I think that looking at it in terms of Embeddability is more useful compared to portability. In the sense that compiling C to any language is easily done without too many problems, what wasm allow is to have a secure and performant interface with that language. For example IIRC one of the first inclusions of wasm was to sandbox many of the various codecs that had regular security vulnerabilities, in this Wasm is neither the first nor the only approach, but with a combination of hype and simplicity it is having good success. as in https://arxiv.org/abs/1912.02285 https://arxiv.org/abs/1912.02285
