There's a node "Cons Cells" in the manual which explains that.

The cons cells are so central to Emacs Lisp that it is impractical to
explain them in each place where we use them in the manual, or even
provide a cross-reference in each such place.

The Introduction manual has a node "List diagrammed", to which you
will get if you type "i cons cell RET", which describes that, with
pictures.

I disagree that it's "theoretical": it's quite practical, and even
includes an example.

So I don't think we have any problems in this area, and I'm therefore
closing this bug.
