Support for Geometric Types

I have a couple questions regarding the maturity of the support for
geometric types:

- is there support for indexing geometric types so that things like '='
operators and some of the other geometric operators are a bit faster?
- are there any plans on extending some of the geometric operators to a
wider range of geometric types? ie: intersects with, contains, etc, to
work on paths and polygons.
- is the developer who originated the types and operators still attached
to the project? would there be any appetite for doing some extensions or
indexing improvements if funding could be found? (I may be able to bring
some funding to bear to support this kind of development)

Thanks,
Paul
