MediaWiki message delivery can't be with bot flag right because the users wont get a message if the bot writing in their talk page.
- Who is they?
- Do bot messages can trigger talk-page notification (I think yes)? Do bot messages mentioning other users can trigger echo notification? (I think yes if signed, but not sure)

This only happens if the edit has a bot flag *and* is marked as a minor edit. MassMessage does not mark edits as minor, so users do get notifications (the whole point of MM really).
