There's one major disadvantage to this model: the .o's can no longer be
considered intermediate files.  That means they cannot be removed after
being added to the archive.

Although disk is a lot cheaper I have had people within the last year or
so reject the "recreate the archive from scratch" method precisely
because they (said they) couldn't afford the hit on disk space.
