I agree. This is saddening. It seems to often happen in "standard first" scenarios for some reason. I was very happy when CloudABI and POSIX were picked as prior art inspiration.

Now it feels like it moved from "what would we need to get things done and achieve our goals?" to "what could be done and which goals could we achieve?"

Maybe I am missing something, but are the recent changes something that people requested?

Yes, you missed people asking for years: away to do interop between languages in WASM, a way to interact with browser APIs without JavaScript from WASM.

Component model enable both using one thing.

Fair enough. Isn't that another topic more tied to WASM compare to what initially claimed to be a "System Interface" and not a language interface or a browser interface?
