It is a good idea in general. Please go ahead, I am sure that the PR will be accepted.

But keep in mind that not always additional links make the documentation better. The rule of tumb is to not add multiple links to the same entity in one paragraph. In many cases the second and the following references are made non-links intentionally. There is also not much benefit of making a link to itself (if the single-paragraph description of the function contains a reference to that function).
