When you put on the chair hat, this statement is really confusing to me.
There are 4 rules in the guideline. Could you please point out which rule you want to mention?
How it relates to my messages.

In the context, we are discussing the document type. And my suggestion is the ISD should be experimental and PSD should be standard track.
Could you please point out how I conflict with the WG consensus?

[WG chair hat: on]

Open does not mean that there are no boundaries. The IETF has code of conduct guidelines (https://datatracker.ietf.org/doc/html/rfc7154)  Please review them.
Violating this code has consequences, potentially including being banned from the mailing list.

The WG has reached consensus on progressing ISD and PSD.  This matter is no longer open for discussion.

I believe IETF is a place working on open standard.
Without open information, open discussion, the protocol can only be private, not be IETF one.
I believe many people share the same opinion on ISD as me.

Operators are not under any obligation to speak to you or the IETF.

I respect your opinion regarding ISD, however, I and many others do not share it.

Reiterating it is not helpful.

On one hand customers cannot provide more use cases.
On the other hand ISD is not future proof, with many limitations.
I do not think ISD is a good way to save bSPL.

NFFRR is one use case, not the only one.

The whole point of going down this path was to stop burning a bSPL per function.

If that really is the only viable use case perhaps we should just have a method of carrying a bag of bits in the stack.

If we have a use case for PSD with cash on the table maybe we should have a different independent method of doing that.

In other words instead of building a universal solution perhaps we should move to a series of problem specific solutions.

I would rather do this with eSPLs but if there is no consensus for that maybe we should use some of the remaining bSPLs, and hope we do not run.

Yes, NFFRR is the only use case I have heard.
But if only for this, there is no need for the MNA. Just some small extension is enough.

I am glad to see this. I am always interested about customer voice. But apparently we didn’t hear here on MNA.

My customers have been very vocal with me.  They want NFFRR support on legacy hardware.
