If some applications relies on
- specific error message in NPE, the application may cease to work, or log parsing will not work anymore, etc
- catching NPE, having detailed error message may slow the application.

so the point to keep the switch is to provide an escape hatch until people either fix their code or use another dependency,
nobody write this kind of code so it has to be in a dependency :)
