Originally from #1716, we propose to remove (without deprecation) the following classes and modules for OTB 7.0.0: * [ ] `OrthoRectificationImageFilter`. Not even used in `OrthoRectificationApplication`! * [x] `Core/CommandLineParser`. Really? (*5pts*) * [ ] `Core/SpatialObjects` We already have OGR for that * [ ] `Filtering/Path` To be checked piece by piece to see if it is really useful (might be used by some deleted or moved out code) * [ ] `Core/ComplexImage` contains only `AmplitudePhaseToRGBFunctor` which can be replaced by typedef of the ImageFunctorFilter and move in an other more suitable module. * [ ] `Core/VectorDataBase` * [ ] `Detection/UrbanArea` contain one filter `UrbanAreaDetectionImageFilter` which is a whole pipeline and two functor, either we create an application out of this, or we keep it as an example, but this is not a proper filter. We think their low usage justifies removal without deprecation.
