Comment (by azaozz):

 Right, using `wp_add_inline_script()` is better in this case.

 However, where is that warning coming from? For back-compat reasons
 `$wp_scripts->localize()` does `foreach ( (array) $l10n as $key => $value
 )`, i.e. it supports passing a string as mentioned in the ticket, and the
 string should be cast to array.

 Does casting to array work in PHP 8.0?
