The reason is that if cross compiling (or for other reasons) python bindings as a whole are turned off. Those two lines then trigger assertion errors unless manually overridden for cross compilation. This way: 1. The `enableNumpy` default respects the `enablePython deafult. 2. Cross works by default 3. Absurd manual overrides still break as they should 4. The `>= 1.65` logic is direct and not a maintaince gotcha.
