The reason why it was originally introduced: arduino/Arduino@a6909bd Why we are removing it now? * Windows does preserve the state of the RTS/DTR bits on successive opening of the serial port. * The serial library used in the Arduino IDE 1.8.x has a bug when trying to set DTR=false, on successive opening of the port the DTR line is set back high by the USB serial driver. This works differently from the serial library we use in the Arduino CLI, that sets DTR=false for good and this change is preserved on the successive opening of the port. * Having the serial port left in a state with DTR=false may cause problems to tools uploading later. It may probably completely removed, but for now, to reduce the testing surface, it will be disabled only for Windows.
