Well, I don't have THAT much real experience but...
In EL you use pageContext to have access to everything in your application that the other Map implicit objects do not offer.

and in Classic Custom Tag Handlers the only way you have access to the application (say you wanna have the output stream by calling the getOut() method) is by the pageContext property it gives you. (OK I know and I've read that classic tags are not being developed that much anymore).

And in Simple Tag Handlers too. well you have getJspContext() method which returns an instance of JspContext but you cast that to a PageContext (which extends JspContext):

PageContext pageContext = (PageContext) getJspContext();

so I think it's not THAT useless!
