I see what you mean.  I'm still concerned about the special case-y nature of this.  Can we segregate by packet number space instead?  Is there any reason not to just say that this only applies to Initial and Handshake packets?  By my rough reckoning, these should all be acknowledged immediately.  Having the transport parameters only apply to 1-RTT (and maybe 0-RTT, which I haven't thought through) is probably right.
