I have no specific advice. dir_to_symlink is hard to get right (the
opposite is easier).

Fear of breaking something, be it upgrades or something else. But I don't
generally buy this as we tend to encourage people to upgrade apt/dpkg
before doing upgrades anyway.

We'd probably have to review the changes since Wheezy to see if there's a
change that would be better reverted, but AFAIR there's no such thing

Some defaults (like xz compression) have changed but the wheezy infrastructure
already deals perfectly with xz everywhere.

Otherwise the backport should be relatively straightforward.
