Ah, here is the source of the confusion. IPv6/IPv4 translators do not use
encapsulation so there is no such thing as an outer header.
I would argue there's no such thing as an inner header.
When you translate from one to another, you take OFF the IPv6 header and
add the IPv4 one.
That's never confused as IPv6 on-path fragmentation because the receiver
is now IPv4.
I.e., this is consistent with IPv4 allowing on-path fragmentation, and
consistent with IPv6 never fragmenting on-path.
