Client credentials middleware should allow any valid client

Last december a change was made to allow any valid client :

Based on the theory and official standards of OAuth2: "The Client Credentials grant is used when applications request an access token to access their own resources, not on behalf of a user." (REF1, REF2).

Shouldn't this change be persistant ?
