This is not a package namespacing issue. This is not a technical issue. It is mechanically no more difficult to change from "@shinn/purescript" to "@whatever/purescript" than it is to change from "purescript" to "purescript-whatever", except that in the common cases (where no disputed community moves have occurred without a corresponding name change) everyone has to include an author. The author can still "give away" or sell package names; a lot the value is not in holding the name, but having the existing installed base and mindshare. These are the social issues associated with a hostile fork.
