I feel like we need a prefix, since this isn't "this" node's name, but the one it depends on / wraps.

Also in the case of multiple outputs -> combiner -> saver. We'd likely want this to be an ordered list for names, and tags to be a dictionary of name -> tags?

Yeah this PR is very much in flux -- I've been thinking it through today and need to solve those edge cases.
