Hi,
Am I right to say that the node library is missing the methods to deal with sections?

All good, I used the dispatcher directly to manage this case. Side note, really liked the following comment, helped me understand I was in the right direction, kuddos!
The internal dispatcher. This is mostly used by the resources but provided for custom requests to the API or API features that have not yet been added to the client.
I think that php library miss these methods too.
