This would just move the problem from having 1968 files to having
to write 1968 lines in control files, and does not solve the problem
of allowing people with an hot-patched old version not being able to
upgrade to a newer (bug-free) version released before the hot-patch.

We maintain multiple stable branches (5, at the moment: 2.5, 3.0, 3.1,
3.2, 3.3) and would like to allow anyone running an old patched
version to still upgrade to a newer version released earlier.
