I think we need to look at this on a case by case basis.

But I also think we need to take this on a "risk management" basis.  IMHO
it isn't critical that we can trace a file back to a specific distribution
point, and confirm the license associated with it.  It should be sufficient
to be confident that the data is released under a license that allows us
to redistribute it.

So, for instance, I was intimately involved in the original release of the
"pci_eg" data files and am confident that the intent was for them to be
redistributable.  Likewise, when we have DTED level 1 files we know that
the government redistributes these as public domain data even if we
can't easily confirm exactly where we got these.

I am concerned that once we remove data files, and drop the corresponding
test suite tests it will be hard to restore this without quite a bit of
work.  We should drop files if we have no confidence in their appropriateness
to redistribute *but* we don't need to demonstrate a detailed trail of
provenance for them either.
