Hmm interesting way of looking at it. As I understand it proprioception is the sense of feeling which identifies the location of parts of the body relative to other parts (and space). You point about learned technique matching proprioception results in "natural recognition" doesn't scan with my understanding (not to say my understanding is entirely correct) - proprioception is a sense, senses (whilst inbuilt) must have interpretation to be useful, for example we all are born with a sense of touch, but it is only when we interact with the world and then other people tell us what that feeling is, do we relate that feeling to the object. To say that hitting a ball a certain way is more natural than another doesn't make sense with this understanding. Providing no method places the body into positions outside it's acceptable range of motion (which as far as i'm aware neither the "traditional" nor "modern" - whatever those terms actually mean - teaching systems do) then neither should be more or less natural than the other. The myelination process makes no distinction between movement - it simply creates and reinforces the neural pathway for whatever movement is being repeated - the more repetition of the movement the greater the myelination.
I take your point about stroke efficiency - I work with a simple premise that I want my players to have "minimum work in = maximum work out" and that proper use of the kinetic chain can result in improvements in this efficiency (stretch-shorten muscle cycle, angular, linear or vertical momentum depending on stance etc), but I still don't take the point that a certain hitting structure is more "natural". It may be more similar to something the player has done before (prior myelination) and therefore be quicker for the player to establish the new pattern of movement/s, but those prior movement are learned also - they are not born into them.
Fun discussion though - this is what Tips/Instruction should be about!!!
Cheers
Proprioception is position sense. Sensory peripheral nerves send feedback to the brain which interprets the feedback and thereby has an understanding of where your body parts are in space, and in relation to each other and surrounding objects. I suspect that pro golfers have extaordinary proprioception compared to the population at large.
I don't know if tennis technique can be characterized as more natural based on proprioception. But, I think it can be characterized as more natural based on biomechanics. For example, IMO, technique that employs upper body rotation as a primary device to swing a racquet is more natural than technique that employs primarily swinging the arm from the shoulder.
