Hello @arbe,
hope you are doing fine. Just wanted to say that Network Component Splitter is a phenomenal node! And extremely fast to my surprise. My approach (for task described here) was two recursive loops and duration was around 5 hours. With Network Component Splitter execution time is around 10 seconds 
And that includes some manipulation nodes as my data is not in a node-node but rather node-value/attribute relation. If this node would have configuration options to handle those cases as well that would be awesome 
Br,
