I'm not sure, I'd have to see what the crypto/tls package does.

I would push back against the notion that something like that is "out of scope" for a "general-purpose user-friendly server". Caddy is far from user friendly if you utilize its low-level JSON configuration API, and at its core, Caddy is an extensible server platform. Even its HTTP app is a plugin, and it can be extended to do frankly anything if you want it to. Streaming video is a use case that I know several people use it for already.
