What granularity would I lose? I think your suggested logic would be
quite equivalent to the one that I originally proposed.

It's possible with the pull model too - the filter sinks are always
traversed recursively. About complexity - I haven't done a thorough
analysis of your suggestion, but I would guess that it would be a little
bit simpler. There would still be a significant amount of added
complexity in the core, though. I'll finish the patch using the original
logic first, and if you want, I can probably do another version to see
how much the push model will differ.
