Comment (by azaozz):

 To be able to disable jQuery Migrate, all `JQMIGRATE` warnings that are
 outputted to the browser console (when `SCRIPT_DEBUG` is enabled) will
 have to be fixed in core, themes and plugins.

 This is a very large task that likely will need some workarounds for older
 and/or unsupported themes and plugins.

 A first step would be to fix all of the (old) js in core. At the same time
 the core js can be updated to use the new features and syntax from jQuery
 3.5+.
