Yes, definitely you want it to also reconnect on the client side as
well. Not just for "completeness" but because it's at connect time when
the device's configuration must be read out and a device which
disconnects and reconnects must be treated as an entirely new device
with possibly different configuration information. So the client *must*
be able to see this disconnect / reconnect.
