I would like to create an issue for changing the behavior of the independent property to be independent both as a source and as a target. That is, an independent item would no longer update when a parent or child of it is updated.
Can I go forward with it or is there a risk of breaking current code that makes it not worth doing this? To me it looks like a bug, but the docs don't say anything about this point.
