| That doesnt explain why it's  needed.

It's  needed for some meta analysis. That's as much as I can say.

| To get community buyin into a feature the community - or at least
| parts of it - need to understand why its needed.

Take a look at these APIs:

    int isNullable(int column) throws SQLException
    Indicates the nullability of values in the designated column.

    NullablePtr [Output] Pointer to a buffer in which to return a
    value that indicates whether the column allows NULL values.

A common and natural question to be answered about result sets.
