1. As part of the work on XEP-0313, two XEPs got split out:

- XEP-0441: Message Archive Management Preferences
- XEP-0442: Pubsub Message Archive Management

I think that at least XEP-0441 belongs into Advanced IM to keep the
same functionality as before.

Removing functionality from a Compliance Suite is problematic in itself? How so? And regarding XEP-0441 specifically, wasn't the functionality optional back when it was in XEP-0313?

Anyway, in my experience, exposing the option to disable MAM can yield undesired results. End users might see no need for a server-side archive if they're not aware of how it helps with reliable message delivery and multi-device support. XEP-0441 itself says:

After observing XEP-0313 usage in the wild, it became apparent that preferences were not often used, and can interfere with clients that use the archive for synchronization of messages received by the user while disconnected. Therefore it is not actively encouraged for an implementation/deployment to offer this functionality.

It seems weird to add this to a Compliance Suite while at the same time "not actively encouraging" implementations to offer this feature.
