The only reason you'd ever want to do that is because browsers offer nothing else, even though they could and at that point why not compile to JS, at least that way your GC isn't being interpreted too. If you're not constrained by the WHATWG's decisions though it doesn't offer anything. It is very use case and "what is the future of your Java application" dependent. Some organizations are looking into migrating off of Java due to a variety of reasons. These kind of "Java conversion" tools help to keep legacy Java applications running until the legacy Java applications can be replaced.
