Pretty good input that can be added to the article:

No persistent connections

As far as I know, at least AWS has two WebSockets based services.

Expensive

I think there are use-cases that are rather expensive to solve with serverless technology, like realtime games and such, but overall? I don't know... many companies I've seen using serverless aren't even getting out of free-tier.

Limited programming language availability

At least AWS has allows to bring your own runtime, it just has to be compiled for Amazon Linux 2.

No local state

I don't think this is a good thing, but I think Azure does something like that with Durable Functions.

Cold starts.

Only a problem if you use FaaS and that isn't a requirement for serverless. At least AWS allows to build some types of serverless applications without Lambda. For example APIs can be build with API-Gateway alone or AppSync.
