Go practice your stalls and steep turns regularly and don't think twice about it. Theoretically, the FAA could re-examine your pilot skills at any time, so you had better be able to maintain the proficiency of the PTS that apply to the certificate you hold. In the Air Force, we're required to practice and maintain specific currency in scores of maneuvers and procedures, to include tactical maneuvering at the "edge of the envelope". It keeps you a sharp stick, and that's important.
Is that a trend these days? It's been since 2004 since I've done any serious GA flying, but I got checked out a couple months ago in a C172 at a local FBO. I tried to let my stalls fully develop and drop a wing before initiating recovery (the way I was taught in primary training in the mid 90s). The brand new CFI was insistent that I recover at the first indication of a stall (the horn), which seemed a little cheesy to me. Is this the way it's taught now? Obviously, in a real-world stall situation, I'd recover at the first clue. But for training, I think it makes sense to understand how the aircraft behaves if you don't catch the clue bird.
