Are there any reasons not to add an additional reference to the cart
panel on the page, so that I could then do something simple like:
((MyPage)getPage()).getCartPanel()
Does Wicket have any sort of assumptions about it & only it
maintaining references between components, such that the above would
cause trouble?

Power is not a means, it is an end. One does not establish a
dictatorship in order to safeguard a revolution; one makes the
revolution in order to establish the dictatorship. The object of
persecution is persecution. The object of torture is torture. The
object of power is power. -- George Orwell, 1984
