> {{CoordinateOperationFinder}} has some corner cases where if fail to find a
> coordinate operation, or a more appropriate operation could be found. Those
> corner cases are identified by {{TODO}} labels in the code. Some cases are:
> h3. In {{createOperationStep(GeodeticCRS, GeodeticCRS)}}:
> * Geographic 2D ⇌ Geographic 3D with datum change: current code can not build
> a Molodensky operation (it builds that operation only when the number of
> dimensions is the same).
> * Coordinate operation performing change of coordinate system (for example
> from {{CartesianCS}} to {{SphericalCS}}) incorrectly named "Affine".
> h3. In {{createOperationStep(GeodeticCRS, VerticalCRS)}}:
> * Information about {{interpolationCRS}} is lost.
