It turned out we had to do it that way -- we're working on replacing node definitions as we know them with something better, but we couldn't do everything in one fell swoop, so we're in a bit of an awkward stage for the moment.
What I've been trying to tell people is: - node scope is special - it overrides top scope - everything (including classes from ENCs!) gets the combined contents of node and top scope - UNLESS it's a class you EXPLICITLY declared outside of node scope. - oh, and don't ever use node inheritance. There might be a better way to talk about that; if so, we'll figure it out as we go.
