But it does fit with the fourth-season theme of finally getting around to the Building of the Federation.  This is counterpoint: how the History of the Galaxy goes hideously, almost irredeemably wrong.  It's what happens if a galactic power built on might rather than communal interest succeeds.  
As a way of showing, in rough form, the consequences of failure, the value of Archer's successes in other Federation-building episodes that season are put into relief.  
That it also emphasizes the very important point that Constitution-class starships rule is a pleasant side effect.
