It may be a way to quickly provide GQL support on top of a Gremlin server. There is a library for it: github.com/WSaffery/GQL...
I can see, however, that the performance of such a setup may not be able to compete with any more direct implementation of GQL.
GitHub - WSaffery/GQL-Compiler: A compiler/transpiler from GQL to Gremlin, with an optimiser built for labelled subgraph queries.
