This is a the quote of the day. From the same reddit link above:

"The feature isn't there for the Group A,B,C players who are better off retrying if they make even a single mistake. Its there for players who are trying to improve and might make a couple mistakes, but still want to keep their time on the board." -- medmondson_rr3

This is consistent with them shifting the gold rewards from B,C players to D and below.
