 Replying to [comment:152 apedog]:
 > My suggestion was to keep {{{jquery-migrate}}} for this cycle so that
 ''no'' plugins will break. The average user would not see ''anything''.

 If `jquery-migrate` stays this release, and gets removed in 5.6, that
 won't change the fact that plugins and themes that won't update for 5.5
 probably won't update for 5.6 either. The exact same predicament will come
 up during 5.6.

 > And again - at the very least {{{.live()}}} should be polyfilled, with a
 dev-targeted deprecation notice.

 Building a custom polyfill, in my opinion, is not worth the effort or
 maintenance burden. That is what `jquery-migrate` is for.

 A deprecated or incorrect usage notice could possibly be thrown when
 `jquery-migrate` is enqueued, but adding back the migrate script would
 cause every site to throw that notice on every page load that loads
 jQuery.
