I also do this. I realise it being in the git repo isn't possible for many companies, but there really should be a diff view. In my project I actually use git to generate a diff (at compile time) that is shown to the user. They can either view the diff to the last version of the terms they accepted, or the whole terms. In that view they can also directly export their data and delete their user account if they deem the new terms to be unacceptable. I think this should be a standard everywhere, but of course it's a futile dream and people don't seem to mind the status quo.
