Alright, fair enough, if it's that easy to get the section and floor data in a human readable format, it's reasonable to do it. I don't like to carry redundant data, but since there's no actual meaningful restriction on data transfer and storage here there's no reason to make my weird design aesthetics somebody else's problem.
That does remind me of something though. Had somebody telling me about Project Silmaril telling them where the teleporters were in Sortie, and how it would give them the exact distance to them. When I said that sounds awful and I'd definitely find coordinates more useful, I was told I was wrong and I couldn't find anything with coordinates, only distance. But the important thing is I had an onion on my belt, which was the style at the time.
So... giving users coordinates for points of interest is useful, but maybe have an optional ping on entering a new floor, giving a direction and distance ("Floor alert! Bihu 120 yalms northwest!") would be a handy feature? It's not perfect, see the whole voidwalker NM system, but it'd be a nice user-friendly touch.
