Sure.

1) My end users are not developers, so this doesn't address the problem.
2) Then none of my scripts will be cached. :)

Here's a really simple example scenario, to describe the problem. Suppose you have an application which allows for a web page to have a "logged-in" mode and a "non-logged-in" mode. If a cookie is present, we know that the user is logged in and needs an additional set of scripts and stylesheets to load immediately upon page load. Certainly I want all those resources for my logged-in state to be cached (!).

The problem arises if I update one of those resources on the server. A refresh is intended to be able to revalidate resources that the page needs, so if a change is made, the local browser cache can update its copy. However, this is not possible. All users will have to wait until a potentially long expiration time on those resources expires before they'll ever get the updates.
