Yes, I acknowledge that during the WG Last Call, you should interpret
the lack of discussion about this issue as an "everything is fine"
feedback. I have nothing more of substance to add and rest my case. You
should stop reading now.


[ As for adoption, FWIW, I would have supported the adoption, but
suggested that the too-narrow scope should be adjusted. Perhaps that
would have been wrong, and you are not overreaching with the "adoption
implies agreement on scope" argument. ]

No, 403 does not imply that I am being forced to block something by a
3rd party. 403 just "blocks silently", not addressing the use cases #1
and #2 in the numbered list at the top of this email.

I do not think it would help unless you are willing to say that the
"legal context" varies so much that it may perfectly apply to blocking
reasons other than the undefined areas of "legal obstacles" and "legal
demands" :-).


Cheers,

Alex.
