As said elsewhere, I think a source package can be regarded as "pristine"
if it is md5-identical with the upstream version in *uncompressed* form.

Even gzip does not compress deterministically.  I learned this when fooling
with the massive X source archives.  I can take the same damn .tar file,
gzip -9 it on different machines, and get different results.  They're not
different by much, say 14 bytes or so, but it is a difference.

Therefore I am of the opinion that we should not in general take md5sums of
compressed files anyway.

In other news, you could always "encapsulate" the upstream pristine source
archive in the Debian source archive, complete with the upstream
compression method intact, if you use the approach that the X source
packages you use.  I think this still counts as "pristine source" because
you can indeed *get* to the pristine source archive.

So either way I do not see your objection as a big hurdle.

But yeah, I'd be happy to compress the X source archives as aggressively as
possible.  bzip2 with the throttle wide open, or whatever.  I wouldn't be
worried about the hard hit taken by uncompressing it, since people without
really manly machines won't be compiling X anyway.
