I would think that at that point you’d be so low that a stall would smack you nose hard on the runway, no time or altitude to recover.
Initially, stall practice is mainly to get the feel of all flight controls during the landing flare. As you slow, the controls become less responsive and you ahve to input more movement, etc., so it's really about feeling the flare.
About the recovery: If you have the idea that you would smack your nose into the runway, you may be pushing your nose over too far for recovery.
I have noticed that some pilots are not trained to recover with a "Minimum loss of altitude". That's what it says in the PTS for stall recovery.
And, as you point out, you don't want to point your nose down into the runway if you do happen to have a high flare accompanied by a sudden wind gust that puts you at 30-50 feet in the air stalling.
You should be powering up as you lower the nose to about level - just enough down to 'break' the stall; recover with minimum nose down, and if you see it will still sink, you can still pull up at the last instant for a belly smack down, not a nose punch into the ground. Really, that's how you should do it. It takes a 'feel' for the elevator; to know when it is recoverd from the stall, but not accelerating more than 3-5 knots above stall. In other words, slow flight. Do slow flight, real slow flight, about 3-5 knots above stall. Ease it into and out of the stall. Get the feel of the flight controls, so that you can recover from the stall with little or no altitude loss.
