This revision is now accepted and ready to land.
This change handles psubus cases with no undefs, so LGTM.
Depending on how the patches land, we could add the undef capability and tests for it directly here or make that an enhancement.
But as I mentioned, I don't think this patch alone is enough to close PR40053 because that's at least 2 independent bugs in 1 report.
