Hi Jerry,

I am back from my a short parental leave and would like to provide my view.

Well, I do hope that better control plane protection can be implemented
in the future.

Yes, I can only concur that it would have been better if this comment
had been raised back then. Now, it wasn't and we have spent 3 years
debating this.

We tried but there was a number of ADs that thought that proposed
standard was not acceptable and forced me to take the decision to
downgrade it to experimental. I don't see delaying publication any
longer bickering around this is any better.

I can see it going to PS with a limited applicability statement as soon
as one have some new deployment data in a walled garden showing that it
works in that environment.
