this is totally up to your requirements. 

We won't persist anything on NonDurableSubscribers. It is like you sending NonPersistentMessages on those cases. So you should decide if you use Durable or not based on your requirements.

We just use UUIDs on NonDurableSubscriptions. You're not required to set the clientID on NonDurableSubscription and you could have multiple subscriptions, so we must use an UUID.

If you like, You could ask a feature through JIRA to use the clientID as part of the ID on
nonDurableSubscribers. I know it would be a simple change...  but I'm not sure if that would make sense or not for other customers.. so Tim Fox would evaluate the request. 

That wouldn't make any difference on the execution of your topics though.
