I saw a rattler at PD once, and damn near got bit at Sand Hills. So, I agree with Mike. The tick problem in Kansas is not to be igored either.
The first photo looks kind of funny, with a nearly square box of the stuff in otherwise smooth turf.
I would never take it away at PD and other places like that, but I doubt I would design it in, either. To start with, depending on wind and climate, the sprinklers cover pretty well for at least 30-40' and maybe a bit more. As Mike says, when you water native type grasses they usually get too thick to be playable. So, for general speed of play, proportional punishment, good watering, etc. I think they should generally be further back from the green than that.
