python/cpython#92199 (comment):

It is not related to this PR, but if some item is mentioned multiple times in one paragrafph, I prefer to keep link only in one of them (usually at the first occurrence). :class:`!OpenerDirector` or ``OpenerDirector``. Too many duplicated links do not make the text more readable.

I agree with @serhiy-storchaka; this would be good to mention in the docs style guide.
