Well, IQ and presence are used for feature discovery in XMPP by the means of
Entity Capabilities (XEP-115) and Service Discovery (XEP-0030). IQ is not only
used for starting file-transfers, but also for avatars and vCards. Sure, vCards
aren’t that common in popular mobile chat apps. However, avatars are.
