Most courses I play with native areas have a thick strip of irrigated native next to the rough that pose both playing and appearance problems. It is difficult to find your ball, difficult to hit the ball if you find it and it looks goofy. It seems to me that setting up irrigation so that the outside rough area is a bit brown before getting to the native would greatly reduce but probably not eliminate this issue.
Are there courses that handle this transition well? How do they do it?
