WebAssembly: A promising technology that is quietly being enshitified

The C ABI approach works fine but becomes complicated when you want to pass things that aren't fixed-length, because unlike the C ABI usage when linking different libraries into the same address space, the host and the module run in different address spaces. Eg if the host wants to pass a string to a module fn, it first needs to call a different "malloc" module fn to allocate some space in the module address space and return that address, then the host writes the string to that address, then calls the original fn it wanted to call with that address, then calls a third "free" function at the end to release that allocation. Does that work? Of course it does. But the component ABI abstracts over all that for you and lets you call the function with the host's string type, and the runtime on the host side and bindings on the module side handle all the thunking so that it appears on the module side as the module's string type.

TFA doesn't seem to have any arguments other than "It's too many new words for me to learn so it's unnecessary I decided." Eg:

>And don't get me started on WIT's kebab-case identifiers (function names, interface names...). Why??? How can a specification about cross-language interoperability can come with a convention that basically no programming language use?

The point of the kebab case is that it does *not* show up in the generated bindings. It's processed by the bindings generator into the appropriate casing for the language. Eg a function name `foo-bar` becomes `foo_bar` in Rust, and a type named `foo-bar` becomes `FooBar`.
