I'd rather see fewer tees than more, with one really being the goal.
Speaking as one of the few higher handicap golfers (hopefully it's on the way down, I have recently discovered this thing called practice), I don't think the current concept of multiple tees is very helpful to us. I am just as likely to hit a lousy shot with a shorter club, unless the difference is something like 4 iron versus 9 iron, which is usually not the difference in tees.
Also, having played many a round with a longer hitter like JohnV, I can tell you that the courses often play shorter for him from the back tees than for me from the regular tees. It doesn't do much good to give me a 20 yard headstart when he outdrives me by 40. And I hit the ball moderately far for a high handicapper.
I always liked the tee markers show in the Garden City Golf Club threads back during the salad days of GCA, way back in 2000 or 2001. They didn't appear to be much more than markers set at the beginning of the fairway, no real boxes or odd shapes. Seems like an ideal worth striving for.
When you try to be all things for all people, you often end up being nothing for everyone.
