It might make sense if LHR, FRA and probably a few others would "see the light" and do like the French at CDG who have now for a few years issued landing clearances on first contact with the tower, USA style. Works well.
Getting landing clearances below 500 (or even below 200) is just ridiculous and adds to workload for the flight crew and increased stress level, totally unjustified, especially when you have a dedicated landing runway (LHR normally).
