[Standards] Re: Proposed XMPP Extension: XMPP Decentralized ID (XID)

URL: https://xmpp.org/extensions/inbox/xid.html

I am unclear on the goal here. It doesn't give us e2e auth, nor does it give us decentralized routing. What can I actually accomplish with this that I cannot accomplish without it? I'm also concerned about formatting them as valid JIDs since this may get confusing on the live network.
