Keyword for page-specific resources

[ferndot]

It would be nice if there were a special name or attribute that could be used on page-specific resources that should be unloaded on navigation.

My use case is that there are pages that do not contain any page-specific resources, but also do not want the ones from other pages to be applied. Right now, I have to define blank resources to bypass the issue.

What do you think? Am I missing something?
