Mike, consider this:
You have a great ODG golf course which suffered from cutbacks in maintenance budgets during the Great Depression and WWII. We'll name this Winged Foot West. The cutbacks were so severe that in a choice was forced upon the club to choose between letting the East course go fallow and be lost or allow the greens to shrink on each course thereby saving enough money that the East course was saved.
This lasted so long, 10+ years, that when the war was over and members back home and monies now available that the greens no longer were viewed as being too small and over time they would shrink even a bit further. Finally in the 1990's it was discovered through comparisons of old photographs that major portions of original putting surfaces had been lost and should be brought back... RESTORED to what they were originally.
If Maintenance is a a feature of design than on-going maintenance, good or bad, must be considered a feature of a RE-DESIGN. Yet no would say that WFW was redesigned yet everyone would say that the greens were restored.
The best part of this example is that is what actually happened in reality...
