Okay, I just tried to install the FD-R9150 with the small metal backup plate stuck onto the band adapter, with the metal part on the centerline of the support bolt, the adhesive portions trailing (towards the rear of bike) and it definitely doesn't fit. When I try to fully tighten the FD onto the band clamp, there's noticeable interference between the body of FD and backup plate, and there's no way I can get the desired 0.5-1.0 mm of trailing edge clearance as shown on page 43 of the DM, even w/ the support bolt backed all the way out. I going to try to cut a small much thinner piece of stainless steel sheet stock with my tin snips and put it on with a thin piece of FSA tape.
