I fully have to agree that it seems like new standards on the Wasm ecosystem are created to get dominion over them. WASI is one clear example of this (but not only, the Component Model is another example where only one runtime is pushing for this).

To be honest, that's not the way standards should be done: standards are named this way because they require wide adoption. Until that happens, they are not standards... just technical specifications.

In general I believe there's a great opportunity to create something based on true Web Standards and not proprietary APIs driven by the big corps, that also can run fully server side.
