"...is there any advantage to trying to make that rim immoveable..."? Yes! Then you can advertise that fact in your four-color tri-fold brochure and sell lots of pianos because the other brand doesn't have what you have! Actually, I suspect there is an advantage - one would likely make the rim more massive and stiff in an attempt to make it immovable - not that you would ever actually make it immovable, but rather you would end up making it very massive and stiff - both good qualities for a good soundboard edge termination associated with minimum soundboard energy loss - which, I believe, is one of the main functions of a "good" rim - that and keeping the soundboard off the floor.
