I've moved this PR out of draft to open as I think the implementation is correct.

Also, I am still waiting on this OCA signatory status verification and I am unsure if it's being filtered out somewhere (i.e., unseen) because the PR was not fully open yet.

The unit tests, in my view, are probably verifying too much (via reflection). E.g., most would usually not write such tests to verify the state of internal arrays.
