I agree with this. I think that in the rush to get their own vision of a
geometry kernel accepted, all the geometry authors let go the notion of
having a single common representation for each geometry type.
Unfortunately as can be seen from the discussions about geometry there
hasn't been consensus on much of anything. Well, beyond the more trivial
things like agnostic compile time access to coordinate sequences (the
bicycle shed.)

I did vote that Polygon should be accepted and still believe it should
based on its merits. I should note that subsequent disagreements have
already come about WRT how data structures are different between GGL and
Polygon (specifically the way polygons are defined). Clearly the
community has so far failed to produce a way of defining geometry in a
form that arguably should be common for all geometry libraries. I
suspect this happens because most of the authors have the goal of
adapting long term projects into a Boost library rather than building a
common one from scratch. I suppose the question is whether the community
should be reinforcing this practice?
