The program includes talks about other layers that Apple is developing. Does anyone know if they are planning on open sourcing any of those layers in the future?
From the description, the "record layer" talk seems like it's about an example POC and not a real project:
> This talk will provide a developer’s perspective building a new FoundationDB layer by describing the design and development of a record store that can provide semantics similar to a relational database. This example layer will provide the core functionality of a structured data store such as metadata management, indexing, and query planning.

The JanusGraph support is a real project, though.
