Agile emphasizes value for the customer but who the customer is has a very broad definition. The end-user is first and foremost, of course, but the operations group who has to keep the service running and the development team who has to maintain it (i.e. you) and so forth are also considered to be customers. If your PM doesn't understand that, it's a failure on his/her part, not an issue with agile itself.
