I think it's useful to have the relay be able to do this, but I'm not 
convinced that it's actually going to get used.   There are relays that 
allow you to configure a delayed relay parameter, but do we know of any 
that are actually used this way?   I don't personally know of anybody who'
s doing this.   I suspect that this is something that's a good idea in 
theory, but not in practice, and because of that, I think it might be a 
better choice to simply leave it out of the spec.

The only reason to even *consider* putting it in the spec is that if it 
doesn't go in now, it will never be possible to do it - if clients and 
servers don't do the right thing from the outset, there's no way to 
retrofit this capability later.   I'm just really skeptical that we're ever 
going to need this, and furthermore I'm skeptical that something like this 
is going to get implemented correctly, when nothing will break immediately 
if either the server implementation or the client implementation is 
incorrect.
