Why does neato not support cluster?

I have a graph that is best presented with neato. However it seems that neato doesn’t support cluster? Here is a test code and its graphic:

graph G {
    subgraph clusterA{
	1;
	2;
	3;
	}
	
}

That’s true. We should generate a warning.

fdp has clusters and makes similar layouts but with different algorithms. (“I’m a researcher not a product manager!”)
