Review Comment:
Yes, technically Bitmap can also use the range-complement path.
However, the benefit is generally smaller than for BTree. Bitmap already
stores nonNullRows as a bitmap, making per-file negative evaluation cheap,
while BTree must scan all non-null key entries and row IDs in each selected
file.
