I like it. I could see myself using this in some places. I would name it `duplexStream()` instead of `duplex()`. I think that's clearer.

Maybe use a `stream.Passthrough`. I haven't really looked into this issue closely though.

Any thoughts on the name? - `.child` - `.process` - `.subprocess` - `.childProcess`

👍

Do nothing. `typeVersions` is meant to add fallbacks.

Not in a way that warns the user I think. We could note it in the readme, but we both know that will not help much.

I like it. I always dread when I have to do anything with Node streams. Observables seem perfect for doing this kind of thing.

It's not possible to intercept the stdout/stderr when you're using `inherit` (Really wish it was though). We could support it on `pipe`, but not sure it belongs here.
