Well, he mentioned ensure-generic, but that only works on procedures.
Also suppose that I have this:
(use-modules (foo goops-module))
(use-modules (bar non-goops-module))

If both of those export the same name, then the non-goops module wins.
Which means it won't matter what the goops module did to defend
against collisions.  I have to resort to using a #:renamer, because
the default names weren't distinct enough.

That said, some conflicts just can't be foreseen, and #:renamer isn't
such a big burden for those cases.  (Personally, I always use an
explicit #:select to ensure I only pull in what I want, and I get no
collisions.)  But I agree with Rob that names should be designed for
readability and greppability; users shouldn't have to go to extra
effort (duplicated in each dependent module) to get those benefits.
