@goose #guix was always meant to be a general purpose package manager from the get go. It did not start as a package manager for scheme code, suffered from an endless cycle of feature creep, and ended up being a Frankenstein's Monster project, if that is what you are asking.
Guile projects tend to use it because it is written in #guile. If you need a package manager for scheme code only, you can try Akku:
People assume you have to know #guile to use #guix - but actually I don't think it's required.
"As a user" it mostly looks like a DSL with functions. More brackets than Typescript ofc - but it's pretty innocent. And less messing around with Derivations compared to #nix
IF you actually start packaging software for it, then you have to get more into the functional experience!
I had some Clojure knowledge before starting on #guix, it was helpful, but not that critical.
