I don't know what you mean by "auto-mapped" -- they used to all map into P.
But it looks like the I fares are active now, with Q/L/V/K fare basis going into I booking class and S/B/M/H fare basis going into P booking class. This now allows them to zero out/limit the lowest restricted FC fares (now in I booking class), while still having separate inventory levels for the upper tiers of the restricted FC fares which are in the P booking class. Previously, P basically served as one big switch for all the restricted FC fares.
