Agreed.
But, it's not it's synchronous nature that's the root of the problem, which I
think you are agreeing with.

I'm not really convinced that the PvD work could ever succeed as it never
quite had the right people at the table.
I think that we would face the same problem today, but at least we have some
benefit of much more experience of these variety of proprietary interfaces.

I don't think that the IETF is the right place to do this work, btw.
But, we do need to be involved as a stakeholder and reviewer.
