ARFoundation with LWRP 5.10.0?

So far have a stable build of ARFoundation and LWRP v 5.6.1 but want to use the LWRP 5.10.0 available from the Package Manager.
https://github.com/Unity-Technologies/arfoundation-samples/tree/lwrp-2019.1


Why?

I believe this is the earliest version that offers compatibility with the Visual Effect Graph!

Has anyone gotten this to work?
