Comment (by DavidAnderson):

 There are obviously a lot of issues involved here. But, for my feedback as
 someone trying to interact with this for WP 4.2 (with a very widely
 installed plugin), it might help to highlight the two most hack-ish thing
 I had to do in order to make my code work again:

 1) The only way to detect when a shiny update had finished was for me to
 use setInterval() to poll and check wp.updates.updateQueue.length. This
 ugliness could be removed by wp.updates.updateSuccess() calling a jQuery
 trigger.

 2) When an update link is clicked, the previous HTML (the update/more info
 links) is lost forever. Shiny updates replaces it with "Updating...". But,
 my code pops up a dialog that has a "cancel" option. If they cancel, I
 can't bring back the previous HTML without ugliness/pain - e.g. parsing
 and saving it all on page load (yuk). It'd be better if shiny updates
 would show/hide the HTML instead of simply replacing it.
