I think the goal might be integrity.
Which means, if you go for something, then flat out do it, do not go for half the result.
That's why a place like Oakmont is great, they had one thing in mind, built a hard penal course and in every detail that's exactly what they did.
When Tom Doak does a course like Barnbougle Dunes, his goal is probably to make a great field of golf, but to make as natural as possible, so every detail is oriented that way with great success.
Probably the same philosophy applies to Raynor's course, fit the templates them fit it all the way...
If you start building just another golf course, or a course that would be like the other one you did on the other side of the country, then you're in trouble.
Basically, try to make every course unique, respect it's uniqueness all the way. It might be green style, bunker style, hell tee style, whatever, but try to reinvent yourself a bit every time.
great artist consistently try to reinvent themself, if you become stagnant, you're dead
