Ah, I get you now. I'd expect typing to be available exactly the same
way as pip is. For me (on Windows) that means that it's available in a
standard install. On Unix, I don't know (I think there's certain
situations where you need to take extra steps in a custom build to
ensure pip is available? I'd expect those steps to also install

So basically, yes, typing can be expected to be available in all
installations, exactly the same as pip is.
