I completely understand that Vladimir is trying to keep it working correctly.
However, I know some downstream project already updated Calcite version and
changed their code to adapt to the Sarg/SEARCH operator. Reverting it and in

Probably RelRule should not change nullability. But we have done so in
the past, and I suspect we continue to do so today. It would be
interesting to find a list of rules that do this.
Deducing that a field is never null is very useful. With that

I am afraid I fail to find a technical justification behind
