This isn’t entirely accurate. A good chunk of nodes have out of the box alternatives now, and for those which don’t you can always build your own. 99% of any automation effort is actually figuring out what you need to do and the order in which you need to do it. Those non-functional Dynamo graphs do just that, quite readily if you’re swapping Toolkit nodes for nodes from Camber or The Civil Nodes.
