I'll repeat what I said over there:
No, "effect" is not intended to cover the response as well. What you
propose is that DELETE either always must pass ("200") or fail ("404" or
"410"), no matter what the state of the server is. This doesn't make any
sense and furthermore doesn't help the client at all.

I personally believe it's clear enough, as the other interpretation
frankly doesn't make any sense.
That being said, what do others think?
Best regards, Julian
