Drivetrain stretching due to lack of parts. Whats you numbers/record?

Going for the 3500Km mark with a shimano XT drivetrain and working. Tool Chain is reaching 1 indicator . Only XT derailer cluch demands regular cleaning.

Wow impressive. With the ongoing shortages, drive chain is being less of a consumable and more of an added value decision for me based on durability and care.

3000 miles on the same GX cassette, but on the 3rd chain. The whole bike is a bit creaky, might be the drive train. But not like it's slipping or ghost shifting or anything, so I am gonna ride this chain and the cassette to destruction.

How much risk would there be to the jockey wheels and front chainring?
