Well, in my opinion neither is a very elegant solution.

Doing a double transformation seems a little messy.  And
is going to make my SVG file HUGE.  Not really good if
I want to transmit the SVG file over a low bandwidth

Well, the coordinates as they are have an instrict value
for the data in the SVG file.  Transforming the 
coordinates would lose that meaning.
