It's both. There will be some messages that users will refuse (for legal reasons) to allow to be stored. But until we have hooks for governance ...

ok

This way drive to put configuration about repository at a different (higher) tier, where the decision of how long we keep them could depend also on which kind of use we would do of them (of course different kinds of analysis need different store duration).

We definitely need some way of defining this as a policy across different "types" of messages, users and scenarios. Plus the capability to say "do not store" (I think we may have that already).
