I chose my words carefully :-).

clientConnectionLost was always a duplicate of IProtocol.connectionLost.

It might be handy to have that notification delivered in multiple places (specifically, for implementing ReconnectingClientFactory), but it's not necessary (there's no "need" for it) since you can clone it by wrapping IProtocol instead of duplicating it in the guts of the reactor.
