In certain circumstances, eg a contaminated taxi way, it is SOP in our company not to put the flaps out until cleared to line up, so it's not always as clear cut as you may think. Also, so TO flap settings may look like little or no flap is deployed, so I'd be very careful before you take action and make the cabin un-secure, thereby creating an RTO.
