Why do you keep repeating this when you know it is not true? We used it in real commercial products and it works as designed. It has scaled for us.

Rather, it's a highly pragmatic engineering (and working
group) decision.

No, If it that was done, it would be a different story. It wasn't done. ADSP was bitterly abandoned and left for dead, you had a major conflict of interest with a reputation/trust modeling framework and vendors in the market place, therefore any add-on (TPA, ATPS) for it would not get serious traction at all. I always felt it will eventually, hence adding the support or the basic DKIM+POLICY into the framework.

You got a different situation with DMARC replacing ADSP.

It is a making a marketing decision when you exclude a perfectly logical, technical and natural part of a protocol out because A) you believe it impugns on resigner operations and B) make instantiated statements that won't scale. That SHOULD NOT be your position within the IETF to stop it from happening. You should support it because it is technically sound. Don't use it yourself but promote not to use it in others in a search for an alternative that is more complex, more insecure and more changes and doesn't resolve the so called "registration" problem,.

Using parato's principle, it will scale for most of the domains because most domains are not Microsoft, Google, Aol or Yahoo. There are more small domains than these relatively few handful. Using parato's principle, most will not have a need to register thousands of list domains and using parato's principle, most can handle even larger big-data problems just fine.
