Comment (by chaion07):

 Thanks @pbiron for reporting this. We reviewed this ticket during a
 [https://wordpress.slack.com/archives/C02RQBWTW/p1658206033254179 recent
 bug-scrub session]. Here's a summary of the feedback received from the
 team:

 01. It would be helpful to respond to the
 [https://make.wordpress.org/core/2022/06/26/rollback-feature-testing-call-
 to-action/ Call for testing], especially if you represent a hosting
 company
 02. Both [https://core.trac.wordpress.org/ticket/51857#comment:259 Testing
 information] and Patches are provided. However, unit tests may possibly be
 difficult to achieve as there currently aren't any for any of the Upgrader
 classes
 03. A [https://core.trac.wordpress.org/ticket/54245 separate ticket
 reported] for WP_Upgrader unit tests as mentioned in one of the previous
 comments. However we are doubtful anything specific to this PR will happen
 before time to consider it being committed. We would also hope, as there
 are no unit tests for this class that it may now matter.

 Cheers!
