Currently a user could be tempted to add mutable state to an interceptor, but the instance will be shared for each spawned actor where it is used.

I think we should either clearly document that you must not put mutable state in it, or make Behaviors.intercept take a factory ensuring (or at least providing guard rails) that a new instance is used for each spawned typed actor.

It is possible we have existing internal interceptors where this has been missed (timers, supervision)
