You're right if juniors take over, but with experience I've learned to understand that things are done a certain way for a reason. Sometimes they didnt see a bigger pictures but many time they did and something blocked them from solving the problem Im trying to solve in maintenance mode.

Commenting too much in the code simply makes my work impossibly hard because I need to juggle with contradictory statements. I ve found that always committing with a ticket reference and keeping tickets forever allows me to go back sometimes decades ago to understand the problem they were solving at the time, for each layer of the code im looking at (each line having an history).

I read comments now with suspicion as sometimes the comment is a commit 20 years ago and the associated line is 5 years old. Should it have always been kept in sync ? Yes. Could it have been ? I've never seen it done properly.
