Yeah, in my case I'm talking about a thing that is largely a web app but also does other things which don't fit well into the one-script-execution-per-request model.
That being said, I would still prefer a monolithic application for a small blog with comments because I think it's easier to manage, deploy, encapsulate, test etc.
I think that this vague definition, right here, is the source of disagreement. Are we talking about small blog with comments?
Or are we talking about one of the services of a medium-sized company, that needs to provide a platform-agnostic API, and real-time updates to subscribed clients with websockets?
