You said it better than I could have. Forcing template developers to maintain separate controller code prevents a lot of good work from getting done in my experience. If the project expands and the combined templates become a problem (usually due to the make up of skills in the team, i.e. heavy on back-end developers), separating them is pretty straight forward.
