That would be inconsistent with the current behaviour with tarballs,
which also contain UIDs and GIDs and AFAIK are kept untouched by
strip-nondeterminism.

If those zipfiles are created in the build target of debian/rules,
why not just use "fakeroot tar czvf tarball.tar.gz file1 file2" or
"fakeroot zip zipfile.zip file1 file2"?

Also: What if the zipfile or the tarball comes from the orig.tar.gz
and we don't want to alter it in any way?

Thanks.
