Landing currency can be a problem, not only on pure long-haul operation. For example we have a fleet that does MFF on both A320 and A330, they have to maintain currency on both types, not only in general. So having to visit the simulator just to do an A320 landing is kinda stupid, therefore it has to be tracked.
JAA logbooks usually do have a column for landings and take off. One can only log those on his PF sectors, if one switches roles on flights take care to only log the relevant part (either take off or landing). It is usually a non-issue for shorthaul pilots except if working part time. PF shouldn't be confused with PICUS, although the brits tend to do that due to their extremely lax CAA view on that thing.
