[Standards] XEP-0484 and multiple devices

Hi, "XEP-0484: Fast Authentication Streamlining Tokens" is written without any considerations for multiple devices. With stuff like that "*For every client using FAST, have two token slots - 'current' and 'new'." *in it. I am kinda confused how the XEP could be considered in 2024. The moment we have two devices for the same user, the devices would start conflicting with each other, by revoking tokens of each other. The XEP should use namespaces (or be resource aware) for it to properly work. -- Best regards, Uvarov Michael
