[Development] Distinguish clients connected to QtWebChannel

inspecting the QtWebChannel code I found that a QMetaObjectPublisher
object is not able to distinquish between different clients. In my eyes
that is a critical part that is needed to support multiple clients
connected to a single QWebChannel.
Because of that reason the feature that property updates are only send
if the client is idling is not working correctly. Imagine two clients
connected to a web channel get a bunch of property updates. The first
client finished processing and sends a "idle-message" to signal that he
is able to receive the next update. The second client is still
processing the first bunch of property changes but will receive the next
update regardless of whether it is able to process it or not. That could
lead to clients that are out of sync.
Also a client can disconnect from a signal but because of not being able
to distinguish the clients all clients will not receive that signal anymore.
Is it meant to be that way? In my opinion the channel should hold the
state of every client instead of one state.
