Change the table to make the EGC size according to the size of the ungrounded conductors.
Or keep Table 250.122, and add a second column for maximum number of Ohms. Add a third column as an informational note, for the maximum length of the default size corresponding to that number of Ohms.
That would meet the intent of the physical issue that they are trying to address. I.e. making sure the EGC has enough conductance to be an effective ground fault current path.
