Thanks for having wrapped up the many discussions on this topic, I was indeed interested by the topic (while non participating for having just a basic knowledge of these objects) but did not manage to get the full thread though. I would suggest in the future to modify the title of the thread when by adding eg [wrap up] or whatever for the list followers to know that the discussion has come to this level. I found Eugene's text great and will translate it into French once there is an agreement on it, but I was also wondering what small and large meant. Is there a (n official) source backing up the 5m width threshold for a ditch?
