Not really. The code called that 3d wire a "neutral" that was also
being used as a ground and the neutral was always required to be an
insulated conductor. I agree a lot of inspectors ignored this
violation but that did not make it right.

Millions of existing installations suggest that at some point the code
did not make that distinction. *Or it was hugely ignored. *Either way
there are a LOT of 10/2 dryer circuits.

Since the 120 V circuit was usually a timer, you did not have much of
a safety issue. If the dryer motor was a 120 V motor, things were a
little less safe. The new rules cover all situations.
