Actually it does make sense in the case where a different package used
to provide something of the same name (and may still) but what it
provides is an older version. Without the complementary
provides/obsolete pair you don't get a clean upgrade path to the
package that should be doing the providing.

As far as I know this is the only case where this is necessary, but
there are several instances of it scattered through our packages.
