I may have overstated the point.   Fragmentation is messy and presents an attack surface, so I suspect it's considered even less safe to pass through firewalls than ICMP Packet Too Big messages.   But you're right that it's not quite at the level of "harmful" to rely on it.

In any case, thanks for raising this.   I think it's a useful discussion.
