Bash is great for cases where you are gluing together a bunch of other commands. But it also has a lot of pitfalls, that something as large and complex as this will absolutely run into (to be fair, so does c). As a specific example, the ACME protocol requires working with json. Doing this in bash is very difficult and error prone, especially if you want to avoid a dependency on something like jq, as this does.
