By "that list" I assume you are referring to Don Chestnut's list which, in 1994, was taken from an article in the Ky. Genealogical Society's "Bluegrass Roots" (Volume 5, No. 1, p. 1-14) written by H. Thomas Tudor. While not all inclusive, it is quite comprehensive (600+ men and women).
Did the Society of Boonesborough provide you with a better list, do they use this list or something else? I would take this as a starting point, as many more would qualify for their Society since they cover the period 1775-1810.
The list copied by Don is mostly the "Original" pioneers from 1775-1781, that I have seen so far. If the other thousands of pioneers are found, they should be added under Project Profiles, not Don's List. If this were a Geni created list, I would agree with updating it. But it's a published work, and an addendum like solution is using Project Profiles for new additions.
