p= DID NOT mistakenly choose to use the language of receiver actions. p=
represents the domain-owner request to the receiver as to the disposition
of messages which fail to validate. Any reading of "concern" is supposition
on the part of yourself or other self appointed interpreters of the mind of
the domain-owner or administrator. The vocabulary is perfectly fine as it
accurately describes the request being made. It makes no attempt to read
the underlying reasoning behind the request because, surprisingly, there is
likely to be a wide range of underlying reasoning behind why various
domains publish the policies they publish. This is an interoperability
standard, not a seance.
