1. You're not running your db on node. It's unlikely that your data will disappear if it turns out node has a bug -> the failure case is much more serious for mongo on docker.

2. You run the even versions of node (noted as stable) in production - they've literally set things up so there's an acceptable way to run node in production.

3. You're showing people how to make a production environment on a system who's creators do NOT want it to be in production. Sounds like a bad idea to me.
