Finalize Warns that it is Permanent Even For PATCH Upgrades

Perform either a PATCH or MAINT upgrade and get to Finalize. The upgrade wizard warns that finalization is permanent.

Your cluster version has been upgraded. Click on Finalize when you are ready to finalize the upgrade and commit to the new version. You are strongly encouraged to run tests on your cluster to ensure it is fully operational before finalizing. You cannot go back to the original version once the upgrade is finalized.

This is not true for certain upgrade types. Finalization is a required step, yes, but you can still revert PATCH and MAINT upgrades that have finalized. The message for these types should read something like:

The PATCH upgrade to HDP-2.5.4.0-1234 is ready to be completed. After finalization, the patch can be reverted from the Stacks and Versions page if it is no longer required."
