So you can certainly choose to spend it on dynamically balancing an already very well balanced assembly of moving parts. However, I suspect 90% of the flying rotaries have not had this performed (except in conjunction with dynamically balancing the prop and entire rotating assembly). If you are going for rpm above 8000 then it probably is worthwhile to do, but at 7000 and below just really don't think it buys you much - if anything. Personal opinion.
