Hopefully, those changes will make it into the final charter (AIUI the Process doesn't give much visibility into that until after approval).

Are any of them (especially the "big guys") offering their implementation, specifications, or patents?

Nowhere did I suggest that, Jeff.

3.5 There's an implementation of 3.6
3.6 There's a proposed starting point (e.g., straw-man specification) for the work that can be referenced by the charter
3.7 The crisp technical problem has been segmented into specific deliverables and bounded by chartered requirements

My experience is that 3.6-3.7 is the minimum bar for viability; if people can't be bothered to write a spec and agree upon it as a starting point, you've got a group of people interested in a problem, nothing more. Giving them a WG is a recipe for a disaster that many of us have lived through, several times.

All I'm really asking for for Web Payments is 3.7, but it seems to be having trouble conforming to "broad" in 5, much less going lower on the JISSR*.

Yes, there are exceptions to this, but I very much disagree with saying that Web Payments is one of those exceptions; it borders on a moral hazard, since we're sucking in a lot of people who aren't used to working in standards.

The number of new Members flocking to W3C to address payments seems to imply that (d) is applicable as well.

Those are all important things to consider when starting the work, but they don't help the effort actually succeed.
