Where in the standards does it say that a packet with any of these headers
should/may/must not be used on the Internet?

I don't understand the reasoning at all. My opinion is that yes, we
perhaps should not create packet generators that send line-rate with small
packets with these headers "because we can", but I see little reason not
to generally create a test that perhaps does a few pps (or less) of
sending these packets (all combinations of headers) to test what happens.

There is nothing on the Internet today stopping anyone with IPv6 access to
generate these packets, so if it breaks the equipment, it's probably
better that someone like RIPE, running Atlas probes, discovers this rather
than a script kiddie out there then posting it to full-disclosure.
