Geometry and Shader nodes : direction vectors of objects
It's very often useful to know the directions vectors of a given object. Maybe I've missed something, but AFAIK it's not always possible with the current available nodes in a shader or GN nodetree.
Knowing the right (+X), forward(+Y) and up (+Z) vectors of the transform (both in local and worldspace) of any object could be helpful in many cases.
And adding these outputs to the object info node should be easy.

One way would be to use Geo Nodes for this. You can output the rotation from the Object Info Node as an attribute and use it in a shader.
This is quite high-level data, which may not always be.
