In my last job, I implemented a transpiler for most GQLs: we supported Gremlin, Cypher, SPARQL NetworkX, GraphQL and SQL. It took me about 3 months to implement each language. We could also convert between different graph serialization formats, like RDF and some JSON formats. The product is now dead (KgBase). The transpiler tool wasn't exposed to users, it was just part of the internal machinery used to seamlessly support many DBs on the same frontend. The graph community should split in 2. Some are interested in graphs from a math/statistics view point, while others are interested in graphs as a generalization of relational DBs. Graph tools attempt to satisfy both camps simultaneously, but their interests and needs are very different.
