Perhaps it's a little misunderstanding.
We do not aim to include the geometry performance results in any
presentation. We've just asked for hosting of this package.
The point is that the geometry performance package is supposed to be
project independent, as objective as possible, ideally if it other
developers could participate to improved it, and so on.
IMHO, OSGeo Community is best candidate to host this initiative,
unless there is a clear objection. Is there?
