My perception of the matter is the other way around.
Take the case of stripped RFC, we can't modify them, hence they are
non-free for us and we don't want to carry them. But they are
distributable and having them on snapshot.d.o hurts nobody.
The same goes for any other non-free material that upstream
includes on purpose (as opposed to by mistake). Say a PDF documentation
or a logo or even a GFDL doc with invariants.
