Neo4j and FPGA

I found couple of old articles: Neo4j on IBM POWER8: Scale Massive Graphs Like Never Before - Neo4j Graph Data Platform and Neo and IBM Teaming Up to Solve Massive Graph Problems - Neo4j Graph Data Platform from 2015 that talk about combining Neo4j with IMP Power8 processor. One of the articles states "The companies did the work to enable Neo4j to run directly atop the Coherent Accelerator Processor Interface (CAPI) cards that IBM uses to connect co-processors, such as Field Programmable Gate Arrays (FPGAs) and Graphic Processing Units (GPUs) to the PCI bus."
I don't see any follow up to those articles. Did the initiative die?
On a related note, is there a way to use FPGAs to speed up Neo4j?
