Good.

Since 2011 library `help-fns+.el' has had that feature.

And it's user configurable - not just on/off, by
option `help-cross-reference-manuals':

1. Choose the list of manuals to search. Default:
   Emacs and Elisp manuals.

2. Choose whether to (a) search systematically,
   when `*Help*' is created, and add a `manuals'
   link only if search finds hits, or (b) always
   create a link, and search only when the link
   is followed.  Default: (b).

`C-h v help-cross-reference-manuals' shows this
(`manuals' is the added link):

---

help-cross-reference-manuals is a variable defined in `help-fns+.el'.
Its value is (("emacs" "elisp"))

Documentation:
Manuals to search, for a `*Help*' buffer link to the manuals.
A cons.

 The car is a list of manuals to search, or the symbol `all', to
  search all.  If nil, then do not create a cross-reference link.

 The cdr is a boolean:

  Non-`nil' means search the manuals, then create a cross-ref link:
        create it only if some search hits are found.

  `nil' means create a cross-ref link without searching manuals
        first (but only if there are some manuals to search).

You can customize this variable.
