But then everyone just wants @fuse/fuse rather than fuse. If one project is @fuse/fuse and the other is @atombender/fuse, the first is going to have more legitimacy, just as if they were called fuse and atombender-fuse.
In reality, that does not seem to have happened, because the top-level is your name, and people have a different relationship to their own "branding", for the most part. People/companies also usually have more than one package.
