By innovating. They have clearly deeply thought about this space and probably have a todo list 1000 items long. By simply copying item 1, you will miss out on the rest until they have been released, etc.
Confusing name as Gremlin is a well known graph traversal language that has existed for years. It's not always easy finding documentation for Gremlin as search results are often polluted by unrelated stuff... this will make things harder still.
I came to the comments to post a similar thing. Was utterly confused how "graph db" and "chaos engineering" go together. Can't you add a distinguishing prefix, like Chaos Gremlin or something like that? I'll start using "Apache Gremlin" for the traversal lang, but that only works if your Gremlin gets a prefix, too.
