   Note that this is not undefined behavior as defined in Rust; the warning is just that when nulls exist, the value of the null slot will be used for filtering regardless of its validity. I.e. it is a semantic undefined behavior.
   
   Do we have some benchmarks available? It would be good to verify that the performance improves here.
