Since wasted effort may prevent other things I see as advantageous to the network and humanity in general from happening, there is a human cost to not preventing it.

You are entitled to your opinion. I do not happen to share it.

There stands some chance. It’s not clear how good that chance is. Obviously you think it is a higher probability than I do. You also assume that it would be widely implemented faster than deployment of IPv6 which is also an assertion of which I remain unconvinced.

Nope… There is historical precedent that you don’t like it. IMHO, we’ve done far too many things and put far too much effort into avoiding rather than completing IPv6 transition. As such, I think that the historical precedent argues that adding to those errors will not accelerate IPv6 transition and is, therefore, wasted effort at best and potentially counterproductive.

At least we agree on something.

IMHO, the proposal has no merit and is therefore a waste of time. Clearly you disagree. That’s fine.

Meh, feel free to do whatever you want. In terms of any IETF WG adoption call or consensus call, I’ll object as I consider it useless at best and harmful at worst.

Nothing you have said provides any indication that there is sufficient merit to be worth the time I have wasted on this thread, let alone further effort.
