da! I have been meaning to bring that up: The module should make the users life easier. "because it will be easier for the module developer" should not be a reason for anything. Also, on the point of backwards computability - I think that can be addressed with a 'backwards compatibility module" that is a shim between legacy application code and a dbv3 module. It would basically be the v2 code that would use the v3 module. it would contain the who's use case for V3 is backwards computability. It would simplify V3 module code and use, and would help V2 applications use V3 modules. It would help channel new development of all code to the simpler V3.
