Importing it during startup isn't necessary per se; imports needed
only by the generic function implementation can and should be imported
late, rather than at the time functools is imported.

However, if pkgutil was/is migrated to using this implementation of
generics, then it's likely going to end up imported during startup
anyway, because at least the -m startup path involves pkgutil.

In short, the overall answer right now is, "maybe", and the answer
later is "rather likely".  ;-)
