- user changes device (or has several client on same device), and one 
notification arrives late for some reason.
- a client is offline, takes time to process MAM and so pubsub notifications, and 
the user mute an entity before it's done.

But I agree that the risk is very low.

Probably not with realistic numbers. I'm just raising a potential issue that 
may never happen. However, if other extensions are used and added to the room 
item, we may reach pubsub item size limit at some point.
