FWIW several of us have shipping implementations of more-advanced functionality so that we know the general road we're on. This should be a subset somewhere (early) on that road, so I think we're covered on implementation experience.

FWIW2, however, none of the implementations I'm familiar with have this proliferation of overloads and multiple option parameters, so we do need to simplify this before presenting it. It's progress though, thanks Lawrence!
