Perhaps we could add a compromise?  Say, modifying the paragraph in
question to read:

     If there is no most recently configured version `dpkg' will pass
     a null argument.

     (Historical note: Truly ancient (pre-1997) versions of dpkg
     passed `<unknown>' (including the angle brackets) in this case.
     Even older ones did not pass a second argument at all, under any
     circumstance.  Note that upgrades using such an old dpkg version
     are unlikely to work for other reasons, even if this old argument
     behavior is handled by your postinst script.)

So historical notes about dpkg are there, but where they belong - in a
parenthetical historical note.  I think this improves the clarity of
the document as a whole.
