Funny you say that because I was talking to an openfaas customer who was using V8 isolates and is moving away from that because have their own issues with mutability.

They are likely going to use kata containers - which can be configured on either Kubernetes or faasd.

The alternative which I've not tried yet is firecracker-containerd
