I can see how that will give you a single-method class some of the time, and I'm in absolute agreement as to how it applies to serialisation classes, but I don't see how SRP implies that single-method service and policy classes are the One True Way.

I think I'll have to give objectify a try and see how it all fits together. It's a different enough approach to what I'm used to that I probably don't have a reliable intuition as to how it'll turn out in practice.
