I don't think closing bugs based on whether they need Launchpad upstream code changes or not is the right line. Whether it does or not, it's a user-affecting issue and it's useful to have a public handle for it, so that we can see how many people are affected etc, and if that's not a bug there's no obvious other place for it. I guess ultimately it will turn into an IS request, but that's not accessible to users and perhaps not worth opening far in advance.
