I guess the reason didn't have to depend directly on monad-logger was
because he/she never mentioned any types from that package by name and thus
didn't require an import of monad-logger modules.

I wonder if we should have the PVP require that if a type you export in
your API loses a class instance, then you're required to bump the major
version number. This would have helped in this case.
