So you could make the cut (be considered a successful exam taker) with a zero score just because a large proportion of your peers got negative scores?

This seems just as unhelpful for deciding who to hire or who to allow onto a higher course of study as the campaigns we have seen on some USA university campuses to give all students an automatic A grade.

That is the cost of equity.

Note that the system also has many holes, so the categorization isn't perfect. Its possible for a large number of students to belong to the categories only on paper. So you don't even get equity in the end.
