We've essentially run into this problem with kupu. Kupu tries not to be 
a widget (we think of it as a client-side in-browser app), but the form 
fetishists at plone.org want it as a widget. When you're a widget, you 
indeed have no control over what goes into that page's header. ZPT's 
macro approach can be interpreted as "you don't need to".

It's really not a problem with JavaScript as <script /> tags can go 
anywhere. It's really a problem with CSS styles which we currently have 
to hack in from JavaScript. XML pipelines would do the trick, for 
example, but that's distant future in Zope, I think.
