”Lots of people” means you? The number of people who have crates of 1980s chains pales in comparison to the number of people using chains of more recent manufacture that should not be connected by reinstalling pins.
I never implied that it was “dangerous” to push pins back in but it can lead to chain failure on more modern chains.
There also is nothing keeping people from using 6/7/8 speed quick links on old 6 speed chains. It’s still a better way of putting a chain together.
Peened pins began with Shimano's 4.8mm spaced 8 speed system, not 9. It didn't come to Campy until 9 because their 8 speed was 7 speed spaced. But the one time pins go back to 1990 Dura Ace.
Well thank you for making my point.
