The WASM component model looks like it wants to free us from the "C ABI" (yes I know technically there's no such a thing) and give us a "high level language agnostic ABI", but when you take a closer look it's really just a hodgepodge of base types from the Rust stdlib in a trenchcoat, so it basically replaces the "C ABI" with something that's a bit friendlier for Rust coders to work with, but that's about it (at least that's the gist, of course there's a lot more than the ABI spec, but that's also a problem of the Component Model: it lacks focus)
