Downloading dependencies on cold start not only adds to start latency, but is also an availability risk. You don't want your starts to fail when the package distribution infrastructure is down. Where possible, it's best to include everything your Lambda function needs to run in the function .zip. That means you can take advantage of all the work we do to make the scale-up and cold-start paths of Lambda highly available and reliable. Having said that, it's very cool to see folks using Deno on Lambda, and getting real numbers like this starts an important conversation. (Disclaimer, I work on the Lambda team at AWS)
