I think this isn't a solution, because of three things: - You need to do this for every other utility simplification. - I dont' like to have more then one implementation if not absolutly needed only for configuration reason. - The activation part on the registration process is still the same. The most problem is that we implement components where using the utility and lookup this utilities by a special name or unnamed. But nobody tells you what name should be used during registration. I still think a policy (somthing like a add wizard) whould solve the problem. Developers can develope the registration process in a pytho class and register tehm as a "utilityPolicy". Then administrators or scripters can add the utility witha simple klick on a "add predefined utility" button. On nice sideeffect whould be, You could also add a policy "Add all utility I need for a site". Or even call this policy during makeSite on your special implementation of IPossibleSite. I think this is what we need at the enduser level and should be possible to implement. Of corse the way we register utilites whould be still available.
