Yes. Path MTU and other things depend on it.

I do. And it seems they don't block ICMP for long. Usually, they block all
ICMP instead of merely ICMP redirects. However, Like I said previously, it
is not compelling that some administrator may make a mistake. It is
compelling that programmers give them no choice.

Fair enough. There are several suggestions on the table for alternatives.
Both of the possibilities suggested by Jinmei work. I suppose a
demonstration of traceroute could be arranged. If you are convinced of
the alternatives, will you agree that reverse should be removed from IPV6?
