Let me know when you've made the requested changes and I'll be happy to do a second review.

One small fix-up for the test, otherwise 🍣

comments is one of the nodes that the feature removes by default. I would recommend doing one of two things here to test the filter:

1. Add a node that the feature doesn't remove by default. Check for its existence before running the removal, then ensure it was removed. Or:
2. Instead of adding a node to the node list in the filter, return an array with only one thing in it (e.g., comments) and then check to ensure that comments was removed but one of the other default nodes (e.g., themes) wasn't.
