This project looks like it's more FaaS style (sans the self-healing / autoscaling etc). Up is more application oriented, it just happens to use Lambda.
(“Serverless”, at least to me, means a platform where I don’t have to worry about running servers.)
I suppose there may be a point to it if the serverless platform is extremely stable and never has any security issues or other things to update.
In general I think 'serverless' means deploying code without managing some kind of server yourself.
