Actually, some operators seem cumbersome to translate to data operations.
For example grouping the selected nodes. The operator will automatically create all the links, inputs and outputs.
To my understanding, if I were to do this with scene data, I would have to script moving the nodes in the group, adding the input/output sockets and making the links, which is Quite inefficient in comparison.
Apparently I’m not the first one to run into a similar issue but @lewis2e didn’t get a response:
