There's nothing new about this. American national parks in the 1980s just bog standard walking from
A to B - it needed permits in quadruplicate with one copy for you to keep, one to drop off at the start point, one at the end point, and I can't quite remember what the other copy was for.
As to monitoring caves, it is best done electronically with loggers, as is footpath footfall generally. What you'll find with paper based systems is that people's ambitions run well ahead of their capability, so they write something in a cave logbook all chipper at the start of a trip that they are going to the ultimate pretties at the very end of the earth, but the reality is they never quite got there, as proved by the counters en route that weren't triggered. And not everyone wants to sign a logbook. And there might be alternative access points that don't have a logbook and don't require permits!!!
I think progressive wear and tear is going to need timeline photography because if the cave conservation precautions like taping off paths are working then there won't be any off-path issues.
