Why not ? The fact is not that any real monitor allowed it, but you 
might sometime have too many windows on your screen, and you still want 
to have the Hatari window visible without overlapping other windows ; in 
that case, zooming some parts but not other could a solution (for 
example, let's say you just want to listen to YM music from Hatari, but 
don't care about the display except for choosing songs in the B.I.G. Demo)

The problem is that Hatari only renders width multiple of 16 pixels, but 
a real overscan line is not multiple of 16 px when you look at the right 
and left border. So either you see too much, or you see too little. Some 
people could be interested to choose their own border size (I agree this 
is less true for top/bottom borders).
Especially, if we consider Hatari could be of use to the remaining 
coders in the ST scene, being able to change the border size can be 
really useful.
