Hi

The concept of a retract is not specific to topological spaces, it is defined for any category as an object which is the target of a retraction (left inverse morphism). I think the article should cover the general definition and provide several examples including the topological case.

Alternatively, you might want to instead an entry to the
existing one which explains the points you just made about
how this concept of retract generalizes.
