I think that nowadays >3.6 can be assumed, especially since the Guix
daemon uses the namespacing features which requires a recentish kernel,
so this doesn't need to be mentioned I think?

It's certainly _a_ library for doing certain stuff, but someone can
definitely write another library for doing that as well, so I wouldn't
use ‘the’ here.
