Does this support generating proofs for non-inclusion? kinda like the ethereum mpt.

Considering using this for generating IBC packet inclusion/non-inclusion proofs as per ics-023

Yes, if you record a proof on a missing value, the nodes along its path included in the proof (proving there is no child at some point for the missing key).
