What if you are remote on an machine (linux or cygwin, does not matter) and
a user has already started a xserver on localhost:0.0. You are not allowed
to connect. So you don't set DISPLAY. If ssh would automaticly set DISPLAY
it would try to connect to an xserver which then refuses the connect. 
ssh would abort because of an error. Not setting DISPLAY means "don't use X"

If users want DIPLAY explicitly set they can add it to their .profile
