Then I think this doc string needs clarification, at least:

---
face-at-point is a byte-compiled Lisp function in faces.el.

(face-at-point &optional THING MULTIPLE)

Return the face of the character after point.
If it has more than one face, return the first one.
If THING is non-nil try first to get a face name from the buffer.
IF MULTIPLE is non-nil, return a list of all faces.
Return nil if there is no face.
---

I think it sounds like it would be more useful if it did indeed return
all the faces at point instead of just the face(s) from either the
overlay or the face(s) from the text property.
