That's a good point. My write-up wasn't clear about that. The spacer juggling around the crank to create the 47.5mm chainline was the critical part for making the setup work with road STI shifters and a front derailleur.
I used the IRD Alpina-d because it's designed for compact chainrings up to about 48-teeth. The Ultegra triple will also work. Most any road FD will work as long as you bring the chainline in from the "natural" 50mm for a MTB crank to something in the 47.5 range.
