It doesn't make much sense. When we rebuild a package without changing
the release, we expect something else in the package to change because
of the rebuild (e.g. a binary will be linked with a new library
version). If the package hasn't changed, it is an alarming condition
which indicates that some of the packager's assumptions were wrong
(e.g. the binary actually doesn't link with the library). So should we
really "optimize" this case? We might as well prohibit it! The
packager should be cognizant that some of his efforts aren't making
any difference. :)
