I had the same question when I found this class today but when I tried to
turn it into a function, I realized that each caller of this function now
needs to maintain two variables instead of one. Since those two variables
(node and distributedNode) need to be in a consistent state, I've thought
of creating a state object but then it seemed silly to create a state
object only and a free function. It's much more natural for it be just a
Having said that, I don't like seemingly excessive use of design patterns
prevalent in some of the code we're adding, particularly, for shadow DOM.
