None of the DSP was changed, if it worked before it should(TM) still
work. The reason we say it's a bad choice is that it was derived for
PSK/PAM signals. The reason it still might work is that the
implementation runs 2 filters at the band-edges and compares the energy
content of those, and that difference might be sufficient to correct
your frequency offset if you have sufficient averaging (i.e. low enough
loop bandwidth).
