Well, the situation here is following: we tried to use JOL internals to walk through the graph, but it turned out to be impossible without substantial changes in JOL. So we decided to merge LJV as an addition to JOL and then refactor.

The plan is to bring LJV as is, and then substitute its graph walking logic with JOL's (maybe in Spring 2023 when I have fresh students).
