It sounds like you’re arguing that we should estimate ‘good done/additional resources’ directly (via Fermi estimates), instead of indirectly using the ITN framework. But shouldn’t these give the same answer?
Use the breakdown of the ITN framework, and actually multiply the importance, the neglectedness and the tractability. I would still call that a Fermi estimate, since most ITN analyses don’t do this extra step.
I don’t think OP is opposed to multiplying them together.

I didn’t suggest otherwise.
