Edge functions are typically run intermittently, with their runtime stopped to free up resources between runs. Therefore a big factor is startup and shutdown speed. Containers are pretty bad there. Deno is better, and WASM is unbeatable, especially with things like Wizer[0].

Deno can in theory do the pre-initialization that wizer does for JS too. We have all of the infrastructure for it, we just have not gotten around to actually implementing it yet.

Issue 3335. I know. I'm watching it. :))

Makes sense when talking about edge functions, but then OP started talking about Kubernetes. Our Kubernetes workloads don't resemble that at all; there's virtually none of that container startup/shutdown overhead to be concerned about. Most weeks, no containers are started or stopped at all.
