Apparently I missed the part of the discussion where it was decided that
adding additional accessors was outside the scope of this RFC.  I had
expected the StartPoint, EndPoint, NumPoints and PointN accessors to be
added.  Is adding them at the same time difficult?  It seems this would
give us a respectible set of accessors (possibly along with something to
access component geometries within a collection).

I'd add it quite bothers me that this sort of functionality is strictly
per-provider and that there isn't generic machinery to provide it to all
the non-RDBMS based providers in a convenient way.

I'm "-0" on the RFC as proposed because I feel a more comprehensive solution
to geometry accessors is desirable at this time rather than just adding things
in dribs-and-drabs.
