SPDB,
It may be a difficult or impossible task, but, you may have to look at the impetus and reasons that the features were removed in the first place to get an understanding on what was the desired intent, and what has changed in the interim.
Then, you have to determine if the club wants to faithfully restore the removed features or wants to make additional alterations.
If a green was disfigured 40 years ago, and the club wants to restore it, I wouldn't automatically categorize that as a negative.
Tee length depends upon intended usage.
If a US Amateur or similar tournament is coming to the club, they may want to make modifications that will allow the golf course to present a reasonable challenge, including the addition of length, which many architects allowed for.
Courses that don't have the luxury of available land have to look to other means to counter the effect of the longer ball.
Bunkering could be used as a legitimate feature.
I think each project has its own unique circumstances and has to be evaluated accordingly.
