Currently in satellite upgrade scenarios foreman-maintain can detect self registration but does not provide any hint/help on how to to fix it. We already have a kcs https://access.redhat.com/solutions/3225941 which we use in such scenarios.

So the ask is to add this article as a hint in foreman-maintain when self registration is detected so that customers encountering this can look at it and fix the issue themselves.
Much like a kcs is provided for a leaap inhibitor/error.
