Ok, i thought you wanted to use the DeepExpression node to calculate those xyz coordinates, which as you say would be possible, but not comfortable. Yes Deep is always camera relative, that's the drawback with it. But as the DeepToPoints node exists, you're right that it shouldn't be to complicated to write a deep to point position node. +1 for the feature request, maybe it makes it into the releas *hope* ;)
