Right, except that flag is per operator in operator class, and what I'm proposing is that the index could pass a flag per tuple in the scan.

That might make sense even for GiST. Sometimes complex compressions is used in GiST opclasses. If indexing value is rather small then it's stored in index as is, but large value is compressed with lossy techniques. So, GiST might return a tuple which is allowed to not recheck.
