Ooof, that sounds like a mess tbh (traditionally, WASI could be described as "POSIX for WASM", and IMHO this sort of focus was just right, easy to communicate, easy to use).

When reading through all the things going into WASI Preview 2 (basically "everything and the kitchen sink", except for async/await(!) which goes into Preview 3) my first thought was: ok, this is what the second-system-effect looks like in practice.

I'd encourage you to read up on the component model. The talk by Luke Wagner linked in other comments is incredibly informative if you can make time to watch it. It's not about replacing WASI, it's about providing a coherent model for both implementing APIs like WASI and also providing structure and tooling for integrating codebases together in a sensible way using WebAssembly.

There is WASIX as a "POSIX for WASM"
