They couldn't be more wrong.  MTU issues still exist, and not just
with tunnelling,
but tunneling should be an expected scenario for IP.

The protocol IPv6 still handles it very poorly,  by still requiring
external ICMP messages,
through the  unreliable PTMUD scheme,  matters are as bad if not worse
than with IPv4.

It's just so unfortunate that IPv6 couldn't provide a good solution
to one of IP's more troublesome deficiencies.
