Yes, I guess I should have made a distinction between torquing the shot and twisting the limbs. Because of the ease of moving the limb tips, it is easier to torque a shot on a recurve by than on a longbow, whether straight limbed or r/d. Not torquing the shot is just one more thing that one has to learn in shooting the recurve, easier than some things, harder than others. Occasional torquing of the string or bow won't ruin a recurve, although it will ruin that particular shot.
When I wrote of torquing the shot in my post above, I meant shooting a recurve with limbs that are inherently out of balance, so that every shot is torqued, with or without the shooter's help. The continuous torquing of each shot eventually weakens the limbs so they will unstring at full draw. You can straighten the limbs so they look in alignment at brace height, but they will bend to the side as you draw the bow.
I didn't know that about the additional effort required to draw a bow near brace height as compared with near full draw. I guess since I've always drawn bows with higher tension in the beginning of the draw, it just seems normal to me, and when I draw a bow without that additional tension, it just seems weak to me. I've never been fond of really heavy weight bows, and fortunately my shoulders are still hanging in there.
