I could be wrong but I vaguely recall this topic, or something similar, come up a few years ago and the RFP was the key. If the ready has been blown then K could not move the ball. If all of this happened before the ready, no foul. Does anyone else remember this?
I don't remember this, but it makes an awful lot of sense to me.
As a corollary, if the RFP wasn't blown and the kicker kicks it anyway, we have a foul for delay of game, just as would happen on a snap, yes?
When teams kick out of the muddle, we instruct the kicker to put his hand up while still in the huddle and blow it in then, for just that reason.
