It is so odd to me as I don't remember a single instance during my 10 years of experience having done that. Only if I was asked by someone else in the org why something is the way it is have I gone to history to see what the ticket number is for the referred change to get an explanation and this is more related to the product.

I wonder what is so different about our workflows, that some people do it all the time and others almost never.

Are we working on somehow very different things.

To me I find that code is the source of truth and current state, it doesn't really matter to me as much why or how something came to be as I look more into how I can make the current thing work with what I am to do.
