I disagree. A signifier gets into semiotics, but more explicitly. e.g. the word "push" is a signifier, but a large bar that makes it seem like you can push it is a perceived affordance.
One could even write a book about the discourse of affordances. It would be boring and irrelevant, but it wouldn't be wrong.
Sorry, just defending the mechanics of meaning.
