Yes.  If you don't prerequest anything, then everything gets
calculated by FE::reinit.  If you prerequest some things, then only
those things get calculated.

It assumes that you want the same things for every p level.  If you've
got some weird formulation that uses only phi for p=3 but only dphi
for p=4, then you'll be stuck calculating both all the time.
