From what I gather the thing is based on WASI which in early beta and for which many parts don't exist or don't work, networking and file access being a few of those [1]: Note that everything here is a prototype, and while a lot of stuff works, there are numerous missing features and some rough edges. One big thing that's not done yet is the actual mechanism to provide a directory as a pre-opened capability, to allow files to be opened. Some of the pieces are there (__wasilibc_register_preopened_fd) but they're not used yet. Networking support is also incomplete.
In other words, this is a somewhat premature announcement when it comes to fulfilling those promises.

That sentence about pre-opened directory capabilities not being supported is actually outdated. They're supported now, so I've now updated the documentation. Thanks for pointing that out!
