Remove penalties for grounding club in a hazard

[Simonko]

Too much to be gained with practice swings in a bunker--I'd be doing three or four quick practice swings tuning where the club enters the sand and getting that unmistakable thud, yet I don't take practice swings anywhere else on the course, not even putting. I think greens would become very sandy.

Lightly brushing the sand on the backstroke and the difficulty proving it means the player will probably escape penalty. That's good, I like self-regulating rules like this. Same with touching small loose impediments on a bridge in a water hazard. Insects moving on green grass, I see that as incidental, like moving dew on grass.

It's too hard to draw the line between harmlessly brushing the sand and removing enough sand to improve the lie, so I feel it's best to err on the side of 'just be careful'.
