Yeah, I feel that - everything was so green in the beginning that getting a Hello World together was painful. When I started, I was still at a big bank, and there wasn't even an IDL selected, so we just started building with SMITHY. Then adopting WIT, etc...
I would say now, especially with AI and Rust, it is night and day. I think as folks come to the conclusion that they care more about what gets built than the how it is done, they start to feel the need for a sandbox. So, WASI P3 is coming along at a really fortunate time. I haven't had any issue nearly oneshotting things directly into wasm with claude.
I appreciate the suggestion on good communities doing it well.
To answer directly, I would credit the PSF and python community with having the best structure that has outlasted my weirdest expectations.
