The two reasons I remember being stated for why slow-start isn't 
necessary the obvious answer are:
 - the transport protocol needs to be robust against the case when the
   route in the network changes from a high to a low capacity one.
 - Not all changes are for the worse; when going from a low to a high
   capacity path then there is no need to make things go slower.
