Is there a 4310-bis document?

I'm curious...is anyone preparing a document?

I confess that I read the thread more or less ten days ago and have 
forgotten the nuances.  The first question is on backwards 
compatibility.  We have already implemented 4310, but, we aren't in 
production with it.  Although we would not want to redo this (As in 
"how do you *want* to pay" want), if we had to for better stability 
we could (consider it).  Considering others are in production, is it 
a given that there will be backwards compatibility?

Are the outstanding issues only related to being able to identify the 
records needed to be changed?  Or is there an issue that the client 
needs to get feedback that the change has been 
regsitered/made/propagated/served?

As with IPv6, the problem with the deployment of frictionless surfaces is
that they're not getting traction.
