alt Hacker News> WASI still leaves something to be desired. Why can't I have raw sockets and file access and stuff, in a POSIX-like way?
FWIW, that's exactly what they shipped first, with WASI preview 1 (wasip1). You can still use this today, and all runtimes with any level of WASI support will be able to run it.
Wasip1 did not specify sockets. Some implementations have made non-standard additions to add them, but sockets were not added to the standard until wasip2.
