I wouldn't put what the RH Sox hitters are doing now in the same category as a bunt. A bunt is intended to be an out, an expense to be incurred to move a runner along. OTOH, I've seen Pedey, Mookie, and Xander intentionally reach out and "serve" the ball to RF. In the worst case scenario it's as effective as a (successful) bunt but in the best case scenario it's a base hit, which doesn't cost the offense 1/3 of an inning. The strategy is much preferable to a bunt, which too many ML players can't do successfully anyway!
My personal favorite, of course, is when an LH hitter serves the ball to an almost vacant left side of the IF. This has to improve the chances of the batter getting a hit.... doesn't it? Shouldn't every LH hitter be able to successfully serve the ball to an semi-vacant left side of the IF more often than one time out of three?
Getting back to my OP three pages ago, if more players would go to the opposite field it would discourage these shifts.
