That's not exactly what the draft says. What it does say is:

  At any point of ICE processing, a trickle ICE agent may receive new
  candidates from the remote agent.

I don't see how trickle ICE would require any changes to the O/A model.
Candidate trickling semantics are completely separate from those in 3264.

Yes, the 3264 offer may, in some cases, contain a first batch of
candidates and the the 3264 may have to be delayed until ICE processing
yields valid pairs for every component but that's about it.

Am I missing something?
