Makes sense if we see the Archive as Store of all messages we have seen.
I often forget thats that the original idea, because of OMEMO PFS i does 
not serv that purpose.

Also if we lose our device, and we want a copy of the archive, we would 
not want to have all groupchats we ever were part of to get our messages 

So for the backup use case this makes sense.

For the message sync between devices use case its not needed/wanted.
