Immunity to slow mode without administrator/moderator rights

I propose to add in the "Roles", then "Access rights" item in the "Text channel rights" section allowing to ignore the slow mode in text channels. As an example, call "Ignore slow mode".
This feature is present if the role has the rights "Administrator" or "Manage messages", but these rights give unnecessary powers.
I would like to be able to let selected people ignore slow mode without additional rights, such as administrator or message management.
Thanks.
