Indeed, I find it very good and it adds a lot of value by referencing
important concepts and giving a concise list of return values.

This style also feels a lot easier to handle, in my opinion, if I refer
to the documentation in order to use other language bindings. Could be
due to fewer uses of C syntax and marking parameters as in/out. I don't
feel burdened with the task to read everything and can quickly check a
single parameter or return value's description.

I think that is true. It would fit many of the current version functions
but describing differences to older versions, for example, may be easier
done with a descriptive text.
