Go-around pitch attitudes vary within a very narrow band, usually 12.5 to a max of 20 or a pitch that yields the correct GA airspeed and keeps it there. Go-around pitch attitudes are a part of the certification process and when flown, are safe. There should be no need to specify pitch.
Experience would indicate however, that there is a strong and clear need to make a call when pitch or speed are either above or below SOP limits.
FDM Programs should be able to help trend what kind of GA performance an air carrier is getting from its pilots, and train accordingly.
Also, go-arounds from altitude, (not at/near minima) require slightly different handling, and a pitch attitude appropriate to the circumstances, not an "SOP-specific" pitch attitude. Here again a call-out is already mandatory in SOPs when any parameter is beyond SOP tolerances.
