Hi, all,
I disagree with the changes indicated in this version.
The new text is both incorrect does not IMO reflect WG consensus.
It is simply false that "it WILL break" or "new protocols can't possibly
know whether fragmentation works" - you even cite studies where this
works the majority of the time (failing 37% for IPv6 DNS resolvers is
succeeding 63%). This is not the same as ICMP-based MTU discovery. Users
absolutely can test and know this.
I repeat my previous suggestion with caps for emphasis- that, LIKE ALL
PROTOCOLS AND FEATURES IN THE INTERNET, IP fragmentation is not
guaranteed to work on any given path and should be confirmed before
being relied upon.
