Thanks for the reply,

control over the software stack is right down to one of the problems: there is not a single software stack, there are multiple ones, so while we may have control over some of our own stacks, we won't have over the ones already out in the wild and which we want to interoperate with. Maybe a change would be possible, but my view is that this would first need consensus (where exactly? here in this group?) and in the "worst cast" an update to the RFC. Would this be a feasible approach at all?

With best regards,
Harald Albrecht
