If it ain't broken...don't try to fix it. ANY and ALL related updates of any sort at this stage only go to fortify DJI''s position of controlling your device if and when the need arises to ground a fleet / calm the FAA.
If DJI thought they could make money on the X5S Osmo handle...its existence would be available or leaked. Cough cough, they'd rather you buy a Ronin product.
And the fat lady sings...DJI is now forcing a update and you'll need to log in or your device is pretty much grounded. Effectively, they are the new UAS registration process to calm the FAA for taking a kick in the nuts.
