If the package is indeed not worth to rebuild it, then there is no
upgrade neccessary on a client's system going from FC6 to F7, and F7
can get a copy of the package (no rebuild) at some later time, no need
to wait for an F7 rebuild in deep freeze to proceed with fixing FC6
bits.

Packages that are the same across dists can be simply copied
over. This is what automagically happens at each new release cycle,
and what you can otherwise ask for. This usually happens for packages
that are known to "never" [1] change across releases, e.g. data
packages, firmwares, fonts. But why not for this case, too, if the
conventional push to F7 is more painful and a rebuilt not really
required?

Note: I'm a strong proponent of rebuilding everything for F7 (other
then data files, firmware and such trivial non-rebuildable stuff), so
having me explain how to not rebuild your packages is contrary to my
religion. But my religion != F7 policy, and the latter asks you to not
rebuild w/o a Damned Good Reason.

Please don't ask me to justify non rebuilding further, I can't. ;)

[1] "never" is relative as even firmwares get installed under
    different paths on different releases, but it's as close to
    "never" as it gets.
