I like this idea, too. I spend a reasonable amount of time trying to
understand what people have changed and if it will affect me negatively
(the defensive part) or positively (for new features, user options,
deprecations). Showing a source-code diff may be a bit technical for some
users, though. I wonder if there could be either a link to a changelog, or
a way to encourage a changelog convention so one could be displayed for
users prior to a decision to update a package.
