Yes, you can if you select Shift or if you click and drag outside of the current range selection dragging in the opposite direction, for example. If you must drag right to left then using the Shift modifier may be your best option. In any case, after deleting you could just click once anywhere to be rid of the current selection and then proceed with dragging.
Yes, it’s a change of behaviour so it means learning a slightly different workflow for certain scenarios. The new behaviour helps in many other situations but means a slightly different workflow in the particular circumstance you are referring to. IMO a change of muscle memory in this particular circumstance may be the best approach.
Having said all this maybe Steinberg could consider a change in behaviour just for the Range tool delete case.
