Comment(by pramsey):

 You can see the logic in _best_srid, however the nutshell version is: if
 it's above a certain latitude, it gets a polar stereographic. If it's
 below, it gets an appropriate UTM, and if it's too big, it gets a
 mercator. We could move to a fully dynamic system, with arbitrary best
 projections fit to the working areas, but would fall out of the SRID cache
 at that point, so performance would drop. And we'd still have maximum
 sizes of objects we could work with.
