Comment (by azaozz):

 > What was the canonical way in 3.8 to say "whoa there, don't run
 autosave"?

 Core used `autosave = function(){};` mostly because jquery.schedule.js
 can't cancel existing schedule properly, it runs one more time. Some
 plugins picked that up too. Don't see any `blockSave = true` when
 searching the github mirror.

 Speaking of jquery.schedule.js, it's not used anywhere in core any more.
 We need a way to deprecate scripts.

 > `.button-disabled` and `.button-primary-disabled` classes were removed
 from JS...

 Thinking they are needed for back-compat.
