If it helps, I can see why it might be useful to find out which other 
OSM objects a node is part of, given that I'm just about to make use of 
exactly that capability in a lua script called from osm2pgsql.  In my 
case it'd be "do something different for information route markers based 
on what route relation they're part of", but I can certainly see why 
someone might want to "do something different if they're mounted on a wall".

This of course echoes Richard Fairhurst's post here back at 
http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2017q1/026289.html . 
Personally I'd find it extremely useful to be able to take say 
https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/style.lua 
and use that as a basis for styling both in OSM Carto and mkgmap, but 
unfortunately I've no idea what'd be needed on the Java/lua integration 
side.
