Comment (by kkmuffme):

 As of PHP 8 any disabled functions aren't included in the functions table
 and can be overwritten by a userland function - WP could define
 filter_input if it doesn't exist in those cases
 (https://php.watch/versions/8.0/disable_functions-redeclare)
 Which would make the argument that some servers don't have filter_
 functions enabled redundant too.
 As soon as WP raises the minimum to PHP 8, this is definitely the way to
 go I'd say?
