Unclear What the disabled behavior actually did for users, and whether this is a temporary rollback or a permanent removal, is not stated.
What
An internal function used at four different call sites (a shortcut-key check and three places in auto-mode's default-mode logic) has been replaced with one that always returns false, no matter what it's given. Every one of those call sites now unconditionally takes the 'false' branch of its logic.
Why
In practice this disables whatever proactive behavior these shortcut and auto-mode branches used to enable, since the check that used to gate them can no longer return true.
