That's already what the TestBot does:

But making use of the Message-Id and In-Reply-To fields could help. The 
would be 3 or 4 cases to handle:
1. Unthreaded patch series (still seems to happen sometimes).
2. Threaded with all parts being replies to the first one.
3. Threaded with all parts being replies to the cover (which is not a 
   patch and thus ignored by the TestBot).
4. Threaded with each part being a reply to the previous one.

I don't think case 4 happens in practice so I'm going to assume it can 
be ignored for now.
