A crack de-stresses timber. So I always do what I do while the crack is open.

But yes, making one part more rigid, say by pinning, in theory places more stress on another part if further stresses are induced. And this may lead to further cracks in the vicinity.

In practice, I have never experienced this happening. Perhaps the stress relief from the crack being open, is sufficient relief in the vicinity for future stresses not to build up high enough to result in further cracking.

BTW, a pin crosses a crack quite close to the bore, and would stabilise the timber there. However I believe that a pin probably does rather little to stabilise the width of a crack near the outside of the crack. A good adhesive filler is probably largely responsible for stabilisation near the surface of the timber.
