Doug's note about ST binder slot length is a good one and a trick I have used on production bikes to "fix" slipping posts at least a couple of times.
To key hole the bottom of the slot or not, that is the question... Having a stress riser free slot bottom is the goal, be that a hole or a U. I have filed a bottom "U" and it grow into a hole as I balanced the shape to much, over and over. Andy
