No server to manage is the least important part of it all. It should describe the abstraction that's actually being offered: IaaS is servers, PaaS is a single app, FaaS is individual function, SaaS is just software.

Any of those other than IaaS itself can be "serverless".

OK, well it's the most important part for me. I don't want to manage patching a box.

Sure, but there have always been options for that, regardless of abstraction level.

I don't know of an abstraction that provides FaaS + Managed System other than serverless - what are you referring to?
