I don’t think that it is described as "just" an extension language. The
website makes it very clear that Guile is also a viable application
language.

Where do you get the impression that Guile is described as "just" an
extension language?

CPython isn’t really nice to embed. Blender managers, but otherwise I
don’t see much good integration.

Isn’t Script-Fu a tinyscheme — with much fewer capabilities than Guile?

Lua does hit the same, but has less default functionality.

Functional doesn’t apply to Guile much better than to CPython.

Currently the default way to embed assumes that Guile is provided as a
shared library. But that can be problematic when you want to ship a
binary people can test easily.

For example I’d like to be able to add Guile to a Godot-game and then
simply ship it.

It would also be nice to have an easy option to embed Guile in Android
apps. "If you use Guile, you cannot turn your program into a mobile app"
isn’t a strong pitch.

I do the same, but I see that this is no viable way forward for existing
programs.

And having Guile in make has already proven useful to me.
