"Actually no. Unless you consider implementing a XEP application specific."

I do. They call these (XEP) XMPP Extension Protocols for a reason ;)

"We therefore invite interested parties to partake in this interesting and very important work, to create a proper IoT protocol."

Implying the others are not? This is not a pragmatic view.
But we are now debating into the noise. Cisco looks forward to the completion of the XEPs we've discussed. They will extend the reach of XMPP into more resource constrained applications and networks.
