:Tired light has a special position because it is the only item on the laundry list that is not based on scattering, and it is the only one that suggests new physics. The scattering mechanisms are covered by a link to the article on scattering. If I come to the redshift article, I would like to have a way to find out about tired light. I think a link should be included, either in a single sentence in the text, or else in "See also".
