In [[Special:OAuthManageMyGrants]], if you manage the rights for an individual application, the "Basic rights" button is greyed out for each application. The user should be informed as to why that is, as right now it looks a bit strange that "Basic rights" can't be removed but everything else can.
Suggestion: something like a little question mark next to the greyed out box, that gives a tooltip saying "Basic rights are required by all connected applications to function properly, and therefore cannot be revoked.".
