We've only used it for label comparisons so far, and what's worse - some nodes to override them some don't. That is very brittle and it's just a matter of time before this causes and issue with a Set or a Map of nodes somewhere.

I've POCed "reference comparable only" for everything that inherits Location in my branch and it works fine.

Also got rid of a lof code mass that was dubious hashCode or equals functions.
