Good question. v1.0.0/v1.0.1 focused on being a drop-in Go replacement (full Go 1.20+ source compat, complete Go 1.27 syntax, cgo support), not WASM/WASI specifically.

WASI networking should work, and stdlib should be fully supported since that's our compat target. Binary size vs. stdlib coverage is likely a tradeoff, similar to TinyGo — haven't benchmarked it rigorously yet though.

Next release (~1–1.5 weeks) will bring full wasm/wasi support with a test report, including size numbers. Will post back here once it's out.
