I think its like the Meese Report in the 1980's - you know what it is when you see it. If you feel iffy when you are writing something, put a trigger around it. If someone else feels you missed something, they will let you or a mod know, in which case a trigger can be easily added. You cant overdo it imo, because it is so easily undone by the reader.

Eta - an example is a specific action. Hows that for non-triggering?!
