> Rewrite directives handled by low-level routing logic of the web server are definitely different to a container image that gets spun up in a distributed network and queried for each request, don't you think?

I’m pretty sure Lambda@Edge is not a container image like regular Lambda (why it only supports JS and not the broader set of Lambda runtimes) and is relatively local to the edge environments serving CloudFront anyway (why it is support in CloudFront the way regular Lambda isn't, and what the @Edge part refers to.)
