@J12t For something like Wiki updates, it may be most appropriate to use a protocol like Linked Data Notifications (https://www.w3.org/TR/ldn/) to notify people that an update has occurred without distributing the substance of the update or the fully updated page.

LDN is based on ActivityStreams. It would be within scope for the SWICG to define the process for publishing and interchanging with ActivityPub.
