I think there is good reason to get worried. My understanding is that third party proposed changes and PRs on the open source version have been denied because they would lessen the benefits of Enterprise. In addition, the lack of certification prevents commercial 3rd party JDK vendors from attempting to support it. Unfortunate, because I'd love to build some prototypes based on graal features, but Oracle's apparent disinterest in supporting community contributions, and the questions around licensing of parts of the graal ecosystem leaves me worried enough to avoid it for now.
