Comment:

 I think this is a difficult change to make.

 There are some valid scenarios where a plugin or theme would be adding to
 or adjusting values found in localized variables. If this were to change,
 it would potentially break backward compatibility for sites.

 I could see adding a way for a developer to tell `wp_localize_script()` to
 use `const` instead, but I think applying this change everywhere by
 default would cause more problems than it would solve.
