I run a standard Ultegra double. I found the whole situation to be pretty silly myself until I was informed on another forum that Trek has come out with a "compact drive" front derailleur bracket to specifically address this issue and that it can be ordered through Trek dealers.
Apparently, it's a standard bracket where the slot gap has been machined to travel a wider distance and range.
Theoretically, problem solved.
