Hmm, well I'd say that if I had a larger chainring up front (than the 53 - not likely but possible) AND the derailleur clamp was rather fat (the Huret is a bit more petite here than many) then the bottom of the diamond could interfere. All this is rather unlikely but the room is there just in case.
What I found interesting is that the water bottle mounts on the seat tube were as low as they are. There is room above the derailleur for them and most frames I've seen in the 55-56 cm range tend to do it this way. Rivendell's way here would appear to be a way to get the center of gravity a bit lower (as I've seen on some older French Randonneur bikes).

Why does your bike have "modified diamonds" for water bottle mounts? Looks like there was plenty of room for front derailleur mounting....
