The difference is that the JIT doesn't "fail". Builds and bundling can fail, and I wouldn't want to trust that all the machinery the builder/bundler depends on (especially if it needs to fetch things over the internet) are available and working properly.

Put another way, as long as the `java` command is present and working on the production machine, I can be pretty sure my service is going to run and work (aside from any bugs in my code, of course). With Deno, more moving parts on the production machine need to be working properly in order to ensure things work properly.
