Yet I can look, for example, at:
http://mirror.centos.org/centos/4.1/updates/i386/headers/
and have no trouble knowing exactly which files were there
at any given date.  Yum could be at least as smart...

The Centos people are doing an excellent job of configuration
management.  If they say they are planning to start deleting
and randomly modifying existing files in their repository instead
of just adding newer ones, I'll give up on it being possible
to tell what was previously present at the points the .hdr
files were generated.  Otherwise, while I agree that yum currently
uses some repo metadata to quickly ignore .hdr files other
than the latest, an option to work with timestamps could let
it construct a view of what was there earlier just as I could
construct a copy of the whole repository as of a certain time
simply by observing the timestamps of all .hdr files - something
that is already viewable.
