Roughing the Kicker???

[Illini_Ref]

Assume NF rules here.

Does the offense have to be in a scrimmage kick formation in order for a roughing the kicker penalty to be called? I'm picturing a 3rd down quick kick. Say the QB is 6 yards behind the line(non scrimmage kick formation), and tries to kick, and is hit just after the kick. Let's say that you would throw a flag on this if it was a traditional punt (scrimmage kick formation). Is it roughing by rule and definition. I notice all the cases in the case book talk about being in a scrimmage kick formation. Didn't know if that was a prerequisite. I know you couldn't have roughing the snapper without the SCF but I don't know about the kicker.
