I hope Tom MacWood answers this question.
You've taken to asking a question a la Pat Mucci rather than including your answer. One Pat Mucci is plenty
Knowing you, Tom Paul, I'd say your response would have to include the test of time component. If something works and the membership likes it, it should be given serious consideration for retaining a subsequent redesign even if it is out of character.
If records exist, I would want to research why it was changed in the first place and then determine if the change was successful. See how if the jigsaw puzzle fell apart a bit as a result.
Then there is a matter of degree, how much out of character and what would be the effect of restoring back to the original in the overall sense of a restoration.
Suppose a green was moved that impacted the next hole? Suppose that green complex is out of character with the rest of the course? I would definitely determine if the green could be moved back and tee length found to make it a good hole again. Then you can fix the following hole as well.
A terrific example of this is the 14th and 15th at Cascades. I cannot imagine why an architect of RTJ,Sr.'s caliber would move the green when there was plenty of room for a new back tee and so seriously compromise the 15th hole. This is the worst offense I've seen in my limited studies.
