Well, sort of.  It's not an issue of efficiency, but of convenience and
just making it possible to do without resorting to manual use of the rpm
command. 

The rpm command "knows" that a new version replacing the old version
supplies the same things that the old one did, so it will quietly allow
the upgrade.  It will also do what we need, i.e. go the other way and
replace a newer version with an older one if you use the --oldpackage
keyword.  We just need urpmi to support its use.
