In section 2.4, would it be easier to implement in existing clients if:
- The response to the iq/get with version 0 was a full roster, in the
existing format, with the addition of the current version number
- The response to iq/get could always be a full roster, if the server
got confused in any way, or know that it would be more efficient to
just start from scratch
- If the roster has been completely deleted, the response would be
empty, but have version 0
- The response to iq/get would otherwise be empty, except for the new
version number
- All changes would be sent to the client as roster pushes after the
iq/response, ordered such that the last one had the current version
number
Then, all I have to do is store my current roster, and apply diffs to
it in exactly one way.

The XMPP Extensions Editor has received a proposal for a new XEP.
Title: Roster Versioning
Abstract: This specification proposes a modification to the XMPP
roster management protocol to support versioning of rosters for more
efficient downloading of the rost er information.

The XMPP Council will decide at its next meeting whether to accept
this proposal as an official XEP.
