Now that IE11 support has been dropped, these polyfills are no longer necessary. This ticket is for discussing when Core should stop loading them. Regardless of when Core stops enqueuing them, they will need to remain in Core in case plugins and themes are declaring them as dependencies for their own scripts. For context, see: - https://make.wordpress.org/core/2021/03/04/discussion-dropping-support-for-ie11/ - https://make.wordpress.org/core/2021/03/25/discussion-summary-dropping-support-for-ie11/ - https://make.wordpress.org/core/2021/04/22/ie-11-support-phase-out-plan/ Related: #53077." defect (bug) closed normal 5.8 Script Loader normal fixed has-patch commit
