No worries! Every time I see a Let's Encrypt thread on HN, there's always complaining about having to trust the official client with root access, webserver configs, dependencies, or whatever. So I made my clients (letsencrypt-nosudo, gethttpsforfree.com, acme-tiny) to shut those people up. My clients are not intended to serve the wider Let's Encrypt target audience, who probably don't know what a CSR is. But for those who do, I made clients that don't ask for the access/trust that the official client needs to serve its target audience.
Thanks for making Let's Encrypt and ACME!
