That may be one of the biggest annoyances of "Agile Methodologies". It's this idea that we can just keep micro-incrementing anything forever. While the principle works great, you end up with this model where you never actually stop/complete/etc...
I'm not saying we should stop that, by any means, precisely the opposite actually, however what we DO need to do is be more focused on actually building sustainable products and services, that generate (gasp) REVENUE/PROFIT, and learn to "Fail Fast" when it becomes a drag.
