UploadWizard does a lot of hacky and probably-unnecessary things. e.g. multiple licenses per batch, a preference for default license, and so on. Let's use stat1 and EventLogging to determine a bunch of complicated things that we can tear out.
This is a tracking bug because we have to integrate EventLogging first, then find the results, then we'll file bugs to remove things we determine we can.
