Comment (by azaozz):

 Looking a bit more at 37110-add-dependency.diff, it may introduce a
 circular dependency (`jquery` depends on `jquery-migragte`, and `jquery-
 migragte` depends on `jquery`) if a plugin restores the way the `jquery`
 script-handle used to work in WP 5.4 and earlier. For example the
 https://github.com/WordPress/wp-jquery-update-test does this with the
 appropriate settings, see https://github.com/WordPress/wp-jquery-update-
 test/blob/trunk/class_wp_jquery_update_test.php#L59.

 If core has to provide an easy way for plugins and themes to still be able
 to load jQuery with jQuery Migrate, something like 37110-add-
 dependency.2.diff will be preferable. Then, once jQuery is updated to 3.x,
 the temporary script-handle can be removed. This means plugins and themes
 that still use it at that point will fail to load their scripts (as a
 dependency will be missing), but will not cause "fatal errors" breaking
 the rest of js.
