PRs show the base branch, but they don't tell how long ago the current branch was updated. Example:

master         A-B-C-D-E  
                    \     
feature-branch       C-Q-Z    

In this case, this feature would tell us that C is the real base

I've wanted to know this in the past, but at the moment I'm only thinking of why we shouldn't implement this: 😅

• Our update-pr-from-base-branch feature already tells us whether it's up to date and it allows us to update it

Discussion welcome. Would this info be useful? When?
