I don't know of anybody using this to update from a tarball to a newer
one. However, I guess some people use this to quickly see what has
changed between the two tarballs. I don't think this use case is covered
by the xdelta3 thing. Maybe it's not a big loss, though?

Hrm, I wouldn't change past releases. Just leave them the way they are;
it shouldn't hurt.

I believe that Debian still uses .gz for the upstream tarball, and at
least in openSUSE, we generally use .bz2 for upstream tarballs (I guess
it's okay to switch to lzma for openSUSE, though). By forcing
downstreams to recompress, we lose the ability to compare the checksums
between upstream and downstream. Not critical, but it was something

Also, there might be tools used by various people that need to be
updated -- not an issue, but this means we'll want to properly announce
the change.

For the rest, I guess it's mostly a matter of habits...
