All software in Debian needs to be Free software - the user must be able to modify and run it (ie recompile after modifying). And for software packaged for Debian that means being able to work with "apt-get source" and "apt-get build-deps". This of course includes dependencies.

That creates a bit of a split between Debian packages and language specific packages like rust crates, golang, python eggs or ruby gems.

There's some friction there, but the reasoning makes sense (but it is ok to disagree of course).

Isn't caddy fully free and open source software?

Certainly AFAIK. I didn't mean to imply otherwise. But FOSS as distributed in binary packages by Debian needs to remain possible to inspect, modify and build via the Debian (source) mirrors - hence all dependencies need to be packaged too (as opposed to living their seperate existence somewhere "go get" may be able to retrieve them from - or not ten years from now - and your respirator depends on a certain version of caddy for it's status display...).

Ahh that makes sense!! I get why Debian maintainers would want that, but it does seem quite hard to manage as a developer. I've went down the rabbit hole of how different Linux distros manage their repository packaging after your original comment so thanks for that :).
