I'm not sure its a good behavior, because SCHC will have to run an
application to do so. Not answering to the ping is part of the incoming
packet processing.

That's the idea, let's take an electric meter sending 4 times a day
measurement. If you don't receive measurement for 1 day you can consider
the device dead. SCHC just keep the time of the last message and when the
ping request arrived and is taken by a rule with action, the dead interval
is computed and if too long the reply is not generated.

The behavior, I was talking about is that you reach this dead interval,
instead of dropping the request, it is compressed and sent to the device.
