Sure, but the centrifugal fuze accomplishes the same safety feature. It can only be armed when it is launched. Setback fuzes use the force of the launch to arm the fuze instead of the spin imparted from the rifling but effectively they’re the same. I’d imagine they found it’s safe enough as is and doesn’t need the added cost of a second fuze.
Possibly but why would they? The centrifugal fuze is sufficient.

Well you learn something new everyday. To be fair I might have learned it ~20 years ago and just forgotten it but interesting nonetheless.
