A lower bound on f values for inverse_time mode (g93) has been in the code forever as far as i can tell but may not be documented:
comment in interp_convert.cc: "In inverse time feed mode, a lower bound of 0.1 is placed on the feed rate so that the feed rate is never set to zero. If the destination point is the same as the current point, the feed rate would be calculated as zero otherwise."
