Actually, no. Pitchers have stashed the stuff on their caps, belt buckles, etc. for years. Then-Yankee, Michael Pineda put a too-visible swath of it on his neck in a game against the Red Sox and got himself ejected for it.
Keep the Rosin bag, allow Sunblock. Hell, give every pitcher a little .5 oz tin of pine tar delivered to the mound by the umpire when they take the hill. Everybody gets the same amount and can use it as little or as much as they feel they need. Starters get a new one after three innings of work...
