Hmm, what was this about then:
"Every function that tries to maximize just height will do it".

Actually you did not.  You showed how to get display pixel sizes.  More is 
needed to correctly calculate the Emacs frame dimensions.
One of the advantage of letting the window manager do it is that it knows 
about multiple displays.  It seems that on w32 you have to figure out this 
yourself.  I guess the lowlevel API functions can be used so that fullwidth 
and fullheight works on w32.  That is so much better than letting lisp code 
calculate frame sizes.
