unsubscribe doesn't delete the topic

[manuell]

Hi,

it seems to me that the subscriptions object is an ever-growing one: each subscribe call will eventually add a new property (the topic string) to the object, but that property will never be 'deleted'.

Is that a "feature? Why?

unsubscribing should never delete a topic (conceptually as a message bus), there is likely a specific delete topic action.
