It's qualified because some names are reused: XMonad.StackSet.focus,
XMonad.Operations.focus

Consistent qualifications make it a bit easier to understand code, but
you can usually tell between those: if you imported both modules as
different random names, the types are sufficiently different that you
can guess which is which (Window -> X ()) is used quite differently than
(Stack a -> a).

I'm not against widespread changes to import style in the name of
consistency, but do take care to address unapplied patches beforehand,
to avoid having to resolve conflicts.
