We came up with a rule “no single use abstractions” so any abstraction with a single caller gets absorbed by its caller. We eventually had to say except across MVC boundaries (the project is MVC organized) or else we got some weird code organizations (controllers consume everything). It works pretty well though, in some cases we have some long methods, but really killed the premature abstraction “this will be useful in the future” discussions that eat a lot of time and energy. I think having a simple rule for everyone makes it easier to follow.
