My concerns about serverless aren't to do with them not scaling - quite the opposite! I'm worried that we'll sacrifice developer experience in the name of "scaleability" of Functions without any real benefit.

Our current hosting costs for the projects I work on are about two orders of magnitude below your "worth it" cutoff :)

The integration stuff you mention is indeed very interesting, thank you for mentioning. I can think of a couple projects that would would really benefit from Functions in this way. Our architect is mainly concerned with scalability here, however.
