Not sure if you mean the same thing, But I think it would be great to have a Use mapping from map > Directly into the Material node.
So instead of having a triplanar, randomizer or even setting Real world mapping in bitmap repeated for every single map, we could just do mapping once and pull that to all maps.
Some materials require 2 or more mapping schemes (e.g some noise map) But for many materials, mapping is exactly the same for every single map. This would allow for much cleaner setups imo :)
