Now we have GNNHeteroGraphs but none of the convolutional layers support them.

See https://pytorch-geometric.readthedocs.io/en/latest/notes/heterogeneous.html and in particular to_hetero for the interface PyG provides.

I am willing to do this.

Has there been any progress on this? Am I correct on assuming that Message Passing is not yet supported for heterogeneous graphs? Thanks!

Yes. Only the basic structure of HeteroGNNGraphs is complete till date. Various graph functions and convolutions are not yet supported.

a preliminary implementation of a convolution for heterographs has been added in #300. Many rough edges though, feedbacks welcome.
