Well, yes indeed. I regard this policy as a set of hardwired privacy
rules per RFC 3921 (XMPP IM), section 10, and more specifically
instances of the examples on blocking messages in section 10.9. The
rules for blocked communication attempts are described in section 10.14:

  If a blocked entity attempts to send message or presence stanzas to
  the user, the user's server SHOULD silently drop the stanza and MUST
  NOT return an error to the sending entity.

  If a blocked entity attempts to send an IQ stanza of type "get" or
  "set" to the user, the user's server MUST return to the sending entity
  a <service-unavailable/> stanza error, since this is the standard
  error code sent from a client that does not understand the namespace
  of an IQ get or set. IQ stanzas of other types SHOULD be silently
  dropped by the server.
