- WARNING: This change is hilariously unsuitable for public instances. Don't run
this code in such an environment yet!
- Groupchat messages are now stored in the sqlite3 database, with the intent
to allow retrieval via MAM at a later date.
FIXME: You can't opt out of this though, which is a huge GDPR hole.
- You can also request ALL of your group chat history from whatsapp be fetched
and stored in the database (!!). This is a VERY resource-intensive operation,
as it involves spawning a metric crapton of threads, uploading a metric
crapton of historical media to the configured upload server, and writing a
metric crapton of messages into the database.
- At some point, the ability to invoke this will be severely limited to only
approved users. That point has not yet come, though.
- Additionally, the chat history request will abort if the connection it's
associated with dies. (You can just retry it, though.)
