I think the question is did the FreeBSD team intentionally (for the
reasons of security) make the default install non-compliant with some
RFCs (read: broken), or was it just not thought of? And second, should
this be changed? I don't think the original poster was suggesting that
deny ip from any to any shouldn't block anything, just asking should there
be a rule in rc.firewall in the default install to allow ICMP so the
machine is well behaved.
