An interesting idea, for sure, but not ultimately what concerns me.  We
actually know the "grouping"...it will be determined by the signature of the
bundle, with broken signatures splitting the grouping.  I was more concerned
with sorting the available versions in a "meaningful" way.  Perhaps this is
too lofty a goal.
