Everything your doing is perfectly ok as long as the productivity gains are there. The lack of a generic function where something occurs 5 times has potential future risk only because it makes refactoring harder. But if you don't deliver a product because your lost building generic things then you don't get to have legacy and support problems. In fact I'd say that until someone is able to quantify the revenue lost and be able to directly tie it against the choices you are making then stay the course.
