KDTree/NativePriorityHeap licensing

[nicloay]

these 2 files mention

// This code originates from https://github.cds.internal.unity3d.com/andy-bastable/SpatialTree
// Check that repo and ask for permission before using it in other projects

as I understand this is internal unity repo. Can we use these files in production or it's only for demo purposes? Thanks.

I would like to know this too, as the SpatialTree / KDTree works wonders.
