Hi, I think this is a great feature that lends it self for several different scenarios.
In our case using one-directional links make perfect sense for references that only need to be one-directional and do not require both Vertexes to be updated on insert. This is particularly true for massive amount of vertexes that reference only a handful of "low cardinality" vertexes. If we did not have this option we would be forced to add hundred of millions of outgoing edges to the referenced vertex without having any real use for it.
