Updates in Navigation should come with notifications for users

One thing we have done, as of 🐛 Create a redirect for the new Block types path Fixed , is establish a UI pattern for how we provide a redirect and BC layer for when we do change paths in the Admin UI. So if a user has bookmarked an affected path in the admin UI, they will get a warning message letting them know about the change.

That helps, but as this issue points out it doesn't really help people who have just updated and are now trying to figure out where a link went that they were previously using for X number of years.

I don't have a solution to that problem yet, and historically, aside from release notes and documentation updates we haven't done anything in the UI itself (that I'm aware of), which sadly seems to be a common practice these days across software, I think to the point where users have come to expect that every update will confuse them by moving things around with no warning.

Help module can provide special section plugin, or even help topic which will be generated from changelog for example
