Just to acknowledge that this is not only theory, it has happened before
actually. Most recently with qtorrent in Fedora 11 stable updates, with
the needed rb_libtorrent only sitting in the koji buildroot. The opposite
has happened before, too, however. ABI-incompatible library updates marked
stable for one or more dists -- after not using rpmdiff, or deliberately
as a result of not knowing the releng buildroot override procedure.

Explicit Requires (with and without versions) also cause unresolved
dependencies regularly (on one or all archs) when pushing updates to
multiple target dists.

Other breakage is caused by automatically disabled features at
%build/%configure time, if a package is mass-built for multiple dists
without accurate/safe/fatal checks of build requirements and without the
packager skimming over build logs.
