Um, yeah?  So what?  Why is this suddenly a problem that MUST be
resolved for filters, when it isn't for current content handlers?
Sure, it might bleed core, but "doctor it hurts when I do that."
This strikes me as rather arbitrary; you're adding a requirment
for filters that has never existed before.  I think that's unfair;
if you must set a minimum bar height, say "a filter model is only
acceptable if each filter has no (or only marginally) more impact
than a content-handler doing the same thing."

Make it even simpler: require the behavioural typification of
a filter that sets response header field X-LastFour to the hex
representation of the last four bytes of content.
