Oh, and if you want to talk Empire - blatant Hoth analogues in the final seige. They even had to have someone say "oh, it's salt" as if to ram home "it's not snow, it's not Hoth, we're not on Hoth!!".
Or it was because it looked like bloody footsteps so the soldiers and the viewers would have wondered what was going on. It was one of the ways the film showed some of the practical trivialities of the First Order - like the ironing robots, which got a big laugh in the cinema I was in. Plus it explained why Kylo didn't slip and slide around and drew attention to the fact that Luke didn't leave the same footprints (I'd have to watch again to see if he left any at all).
But no, the negative explanation is the only possible one. Obviously having mentioned the name of the planet numerous times they were making the name clear again, that's all.





Or has he?
At the very least he's going to appear as a ghostly yoda style apparition on some godforsaken planet when whatever she's called is having a dark teatime of the soul.
