eg, you don't want your jumpers going through the same holes as 
component
pins.  (Hmm.  Probably.  OTOH, it would cut down on drilling, and 30g 
Wire
doesn't take up much space.  OTTH, I tried this once and it was a 
pain...)
You don't particularly want jumpers that go UNDER other components 
either.

I you're trying for a single sided board, hopefully the number of 
top-side
traces will be relatively small, whether or they connect through pins.  
In
that case, it is relatively easy to move the jumpers off of the pins to 
a
more convenient location...
