I have run a TA 46T chainring on a 4 arm Chorus crankset with a matching 2015+ FD. FD shifted perfectly, in fact the lower position opened up a better angle to the cassette and I got a completely trim-free setup across the board.
Problem is that you cant fit a 34- small ring and the small jump upset my upshift/downshift habits so I changed back to compact.
But the 46 front shifting absolutely no issue.
