The monad interface predates the file-like stuff in (guix gexp).
The “regular” gexp/file-like interface today is sufficient in a wide
range of cases, such that it’s normally not necessary to use the monadic
interface unless you’re getting into internals or writing a new tool.

Which is not to say that the usability problem must be ignored, but
rather that it should be put in perspective, in particular to better
understand the needs of those who end up struggling with the monadic
