The problem of breaking encapsulation:
I did some work on this problem on my own a few months ago, my solution was
to use a header contrib manager, and instead of adding files with a header
contributer i add them to the manager, then get a single contributer per
page from the manger.
for example in a panel you would do
@Override
protected void onBeforeRender() {
super.onBeforeRender();
ResourceReference rr = new ResourceReference(getClass(),
"test.js");
WicketApplication.get().getHcm().add(rr, getPage().getClass());
}
See how it uses getPage().getClass(), so the manager knows which class the
panel is being added into
then in the main page class
@Override
protected void onBeforeRender() {
super.onBeforeRender();
add(WicketApplication.get().getHcm().getHeaderContributor(getClass()));
}
since the manager knows all of the resources added for the page at this
point, it is easy to compress them all together and serve a single file, and
you dont have to list the files up front.
What do you think of this idea?
My code is here:

It still has bugs etc in it, and doesnt really work cos ive messed up the
registerResource method, but you should be able to get the idea from it
