pristine-tar hat tricks[1] aside, none of gzip, bzip2, xz are required
to always produce the same compressed file for a given input file, and I
can tell you from experience that there is a wide amount of variation. If
multiarch requires this, then its design is at worst broken, and at
best, there will be a lot of coordination pain every time there is a
new/different version of any of these that happens to compress slightly
differently.

Maybe there was a reason for Guillem  to want to tread carefully.
