The upgrade guide already mentions this specifically.

Thank you for your mention, but most users did not go through the user guide before the upgrade. I think it is more useful to show the older boot environments to the users before the process of upgrading. Thank you.

The upgrade guide is mentioned in the release announcement on the blog, and it's the official place to find information about the upgrade process. We cannot repeat all of that info in every copy of the release notes, and there is no reliable way to predict that the next BE will run out of space. We are working on the backend side of that to clean up older BEs automatically, but that's being tracked separately already. Forcing the user to click through BEs at each upgrade would cause more confusion than it would save.
