Does the use of positional embeddings mess with the gnn for formulation? I'm not familiar with the requirements for something to be a gnn, but positional embeddings mean the graphs have to capture order of occurrence, and the graph in the shared page doesn't seem to do that.

In graph terms, Positional encodings are useful for adding sequential/temporal properties to each node in the graph. Indeed, there are works on position-aware GNNs.
