Exactly. Macros must be avoided in many cases, but registration is one
of the widely accepted use cases. See Boost.Math default policy
declarations as one of the many examples.

So if the whole point of making a facade that hides the many traits is
just to avoid macros for the principle they're bad, I'm afraid I just
don't feel the need to do that.

GEOMETRY_REGISTER_POINT_2D(my_point, double, cs::cartesian, x(), y())

Just to be sure, what does it give with your approach?
