The next round of renovations at MV will probably be carried out by one of his many current (or former) associates, who would be trusted to understand what JN was trying to accomplish, I think.
The counter argument to "that's your opinion" (or for restoration of any course to it's architects original intent) is that they experience changes of heart and philosophy over decades.
Jack has had on many design issues over his long career as a gca. We tend to think of Ross and his philosophy, but I believe it changed from the 1910's to the 1940's, when he did his last course.
Here, the most instructive thing Jack could do was pen an article (or have it ghost written) about how his philosophies have changed from 1969 and Harbor Town until today. I presume he would consider today's views as his highest and best. Otherwise, he would go back to some previous version of his design philosophy.
BTW, I would love to hear what Jack thinks is a good slope for a tucked pin position to make it more receptive to pros. I have had this discussion with other pros, and they think a certain amount is good, but too steep, and it is problematic, since they tend to hit higher spin shots to the back of the green when clearing a bunker and a steep slope might make it check back too far.
