Ah.  Two answers to that one:

(1) I'm only really considering output filters.  Input filters
    can't depend on the handler, so the dynamic configuration
    discussed is not relevant to them.

(2) I propose getting rid of it because I cannot see any circumstance
    in which it's necessary in an output filter.  But it's not a
    requirement of the proposed archictecture, except insofar as
    it saves the overhead of a filter initialising when it's not
    going to be run.
