No,

1. Using <updateOneway/> in the SubscribeQos will switch to updateOneway()
   for exactly those messages which are delivered for this subscription.

2. PtP messages currently can't force updateOneway explicitly.

3. Using the attribute <callback oneway="true" ...> in ConnectQos will switch
   on updateOneway() for ALL callbacks of this login session (including PtP)

With variant 1 you have fine control on which topics shall be delivered oneway.
