I think it's a decent architectural decision.
It's a lot easier to develop solid code that handles a single request than code than handles multiple requests in parallel.
Functions are used for a lot more than HTTP, we use them for a lot of DB event handling such as post-processing, in which case cold starts does not really matter.
Maybe we'll one day get to a point where the cloud service knows the best way to run our code?
