I'm not sure this is reliable, but you can Preview contents when you
go to create an Asset with Transform, and choose to include all
inputs, Including Shading Networks.
When you Apply this preview, you'll see selected all the nodes that
would end up in the asset had it been made.  (open Hypergraph
connections)

Default nodes will not go into assets either.
