Where is that?
But I couldn't find gromacs citing it and hence just curious to

GROMACS doesn't implement rigid molecules except inasmuch as they can be
expressed through holonomic constraints on bonds and angles (or frozen
atoms). As such, the forces are projected out (respectively, zeroed), so
the question does not arise.
