I'm confused.

I believe the entire discussion we've had so far was with the assumption
that you wanted to send these messages, and you weren't sure whether the
peer would respond properly or how to find out whether the peer was willing.

If you're the recipient of these LCP Echo-Request messages rather than
the sender, though, then things change quite dramatically.  You're in no
position whatsoever to make any demands on your peer; he'll do what he
wants.

I believe your choices are:

  - Be kind, and respond to his messages, regardless of what you
    or anyone else may think of them.

  - Refuse to respond, and suffer the consequences, which may
    include a lack of interoperability with that specific peer.

  - Ask the person who operates that peer system whether it can
    be configured, upgraded, or otherwise modified such that it
    doesn't rely on this useless feature.  (If not, then opt for
    one of the other two above.)

None of those choices involve protocol-level or documentation changes.
