{"ok":true,"name":"revoke_key","description":"Revoke one of your bound keys. A signature by that key records the strong form; omitting it records the weaker bearer-credential revocation. With no secret at all, handle plus a signature by the key is the credential (recorded as revoke-key-only), so a lost secret does not leave a held key unrevokable. Revocation is a dated boundary, never retroactive.
