Because in some cases the aspect whether or not the language is functional is not the only decision criteria for the choice of language. If it was, I would absolutely recommend to consider a language than go. But if go is selected because of different criteria (i.e. interoperability with an existing eco-system, cross compilation support, FIPS compliance, ...) then this library can help to apply fp paradigms in you go code. Hopefully to make it readable and testable.
