The owner-token may solve the problem, but there is no technical reason
to restrict owner-email not doing that as well, plus giving a mail
address instead of letting the victim figure out who to ask.

I would be glad to see that included!

Now I am really confused.  I thought the owner would be the user the
script belongs to, not the admin of the sending system.  The admin should
always be able to figure out abuse.

Anyway: If we can agree on "it's implementation-dependent", we don't
have to define further terms, and it addresses all my issues.

Perhaps that's a good idea, despite showing something that depends on
the implementation, but at least people see it does!
