Which is why I said "like this" as this bundle of threads started
with spoofing of DNS queries.

Indeed.  Those are exceptions not the rule.  How many residential
connections would be doing SAS for testing, compared to configuration
errors or as the result on criminal misappropriation of equipement.

When both configuration errors and spoofed traffic as the result
of criminal misappropriation of equipement both should be dropped
what are the courts likely to find?

Even with SAS for testing you can filter based on MAC / port / link
so only designated machines can send spoofed traffic.

I certainly don't want to be the subject of a test case.
