workerd is missing the scheduler - the thing that allows it to operate across nodes. Durable Object storage are just local sqlite databases.
celld is the full distributed system (albeit single tenant). It distributes DOs (cells) across any number of VMs. The databases for each DO are in object storage with RPO=0 guarantee.
You beat us to it! Been meaning to land this but got distracted.

But honestly I love that there are multiple implementations now.
bummer this expects NFS; this is all a brand new implementation vs what Cloudflare runs internally in production for DOs? I can’t imagine all your workerds share a single global NFS… What would a more realistic workerd with DO support look like?
ah well, we have celld!
