Well, I've already suggested that only bugs that potentially lead to 
privilege escalation/intrusion (local and remote) would be candidates. 
This probably includes any kind of buffer overflow or "wild write" bug.

Clearly, a bug should also be present over a complete release cycle 
before it's worth annotating. A bug introduced in -rc1 and fixed in -rc5 
is NOT a candidate.

Thanks! Without making any promises, I am fairly sure that my team has 
an interest in adding and maintaining triggers.

Based on some of the later comments in this thread, I think it might be 
a good idea to keep a separate git tree for the triggers for a while. 
You are of course welcome to contribute in any case.
