Some probably would, but I think you're right in that PWM is probably the
dominant output for control systems.  Either the thing being driven is
modulated by PWM directly like a motor or a solenoid, or the PWM is filtered
into a analog signal that is used for old fashioned control.

Higher than what?  I think you are responding to comments on floating point,
but encryption is done with integers anyway.

In any case, you can certainly come up with reasons for needing more than 16
bit accuracy in special cases.  However, I think those special case are
unusual or even rare in the kind of real world control applications PICs
find themselves in.
