Right - if you're doing a single upload, that's what has to happen anyway;
you can't let the same package get picked up by the buildds for multiple
releases, because then you would have multiple binary packages with the same
version numbers.

If you want the packages to get rebuilt separately in each release, you can
tack a 'buildN' on the version number and upload separately.  If you want
the same package version to be used in all suites, a pocket copy will do
that.  Either way, it should not be necessary to implement anything new on
the Launchpad side to handle twiddling of upload targets in the .changes.

FWIW, the .changes semantics support specifying multiple upload targets
because Debian used to use this (er, about a decade ago) to designate
packages that should be installed both to the 'unstable' and the 'frozen'
archives.  It's no longer supported in the Debian archive, because of the
ambiguities related to how the binary packages should get built.
