I see in Spacing_engraver::stop_translation_timestep():
SCM proportional = get_property (this, "proportionalNotationDuration");
if (unsmob<Moment> (proportional))
{
set_property (musical_column, "shortest-playing-duration", proportional);
set_property (musical_column, "shortest-starter-duration", proportional);
set_property (musical_column, "used", SCM_BOOL_T);
return;
}
so it looks like you can remove it.
