You won't get back the same MD5 checksum after tar and gzip of the same
files, even if you set the UIDs.  pristine-tar has various additional code
to deal with all the various changes created by the tools.

However you generate the .orig.tar.gz file, you can then manage it with
pristine-tar, at least if you're using a VCS that pristine-tar supports.
The process when you repack upstream is really the same as when you just
download upstream from pristine-tar's perspective.

The big one is that the timestamps will generally change (particularly on
directories), and gzip also encodes a timestamp.  There are other minor
differences generated by minor tool changes.
