What I do is to treat the HEAD as a separate View in it's self, so you can
use either a common template for site wide, or a more specific template for
any given request.
Thus, I can add Javascript, Meta Tags etc on demand, without effecting the
rest of the system. On another note, I think it's a bad idea,
architecturally, to be dependent on using plugins to aid in your output
generation.
The functionality and facilities should already be there, available in a
lower layer.
