Comment (by apedog):

 > The outline and plan that you described is exactly what jquery-migrate
 does [...] this method of bringing compatibility issues to their attention
 is not going to work for the remaining plugins and themes.
 Not ''exaclty'' the same. That's jquery-migrate throwing those notices.
 Not wp-core. There never was any need to fix those issues. They could be
 safely ignored. jquery-migrate would pick up the slack. It's not the same
 as wp-core giving specific notice about WP deprecation ''of'' jquery-
 migrate. Perhaps with links to the relevant notes. That's "aggressive"
 outreach :) A canonical plugin for this purpose would work. Keeping core
 clean of any transitional fix.

 I still think giving an extra cycle for users to enable auto-updates, and
 then for plugin devs to be notified (via canonical plugin/console, email
 or both) of this deprecation will lead to a smoother transition and less
 user-side breakage. Breakage (of core's {{{common.js}}}) upon upgrade is
 guaranteed as things stand now. There are simply enough plugins in use
 today that rely on jquery-migrate, and not enough ''(any)'' users auto-
 updating to avoid that. Auto-updates needs to go in first.

 This might mean pushing some of the jQuery Upgrade milestones back by
 one.. :(

 ----
 @archon810 "Trac UI Preferences" link at bottom right of this page allows
 adding "Never Notify" subscription rules. That might do the trick.
