This undocumented feature only works in lexical-binding buffers.
And there's no need to post bug reports about things you're wondering
about, especially when you're also discussing this on other Emacs
mailing lists.

My questions here would be:
1. Why is it undocumented?
2. Why does it work only for lexical-binding buffers?
___
:documentation is documented in the Elisp manual,
but only for `cl-defgeneric'.
(Grepping the Lisp source code shows there are :doc,
:doc-spec, and :documentation. :doc is documented
in the Elisp manual, in the context of defcustom.
:doc-spec seems to be documented in no manual.)
We don't document everything, of course. But should
:documentation be documented for defun, as well as
for cl-defgeneric?
Yes, the latter is an emulation of Common Lisp's
`defgeneric', which has :documentation. But defun
also has it now, apparently.

I put it as it did seem a difficult problem that still remains unsolved.
