The force of a couple of halyards should not be enough to elongate holes in the mast.
When I replaced the mast step in Windburn I doubted I would get the height exactly the same so I made up adjustable mast collar hold down clamps. I can see the deck rises a bit when the shrouds and backstay are tightened, so as a starting point I make the clamps snug with the standing rigging tight and a 50% on backstay. I am using the clamps to only take the flex out for the halyards, not to try to overcome the "set" caused by the standing rigging. The theory is that wind gust will transfer force into the halyards, cause the deck to rise which in turn simulates easing the halyard. Exactly what you do not want in a gust. If the clamps are tight before the standing rigging is tensioned, and if there is a slight bit of softness in the mast step I could see where a lot of force is going to be transferred into the clamps. I don't think that was their original design intent.
