Well, I wouldn't want to be responsible for any further destruction of the Internet revolution, but most of this seems besides the point. Old-style PMTUD, which *depended* on the delivery of ICMPs, is a far cry from new-style PMTUD, which *can benefit* from the delivery of ICMPs. The problem was the PMTU algorithm, not the idea of ICMPs. And the network isn't full of useless ICMPs.
Nonetheless, I believe we should keep options open and investigate ways to support L2 devices that don't send ICMPs and don't support IP fragmentation without relegating them to second-class citizens. PLPMTUD gives us one such tool, but does it *really need* the ICMPs?
We got this wrong on the first iteration some 15 years ago, and if there is now an opportunity to set things right we should at least give it serious consideration and make the right informed decisions.
