 3. retries: It's highly unusual that my request will not proceed as function instances are ephemeral and failing function is immediately replaced with a new instance. If it happens I can easily send another request. In case of failure, it's easy to understand what is the cause.

 Tools like Envoy/Linkerd solve different domain of technical problems that doesn't occur in serverless space. They have a lot of features that are unnecessary in the context of serverless computing.
