This has been suggested multiple times over the years.

I added it to *Help* in my library help-fns+.el in 2011.

A user option controls whether such a link is shown, and
if so, which manuals to check, and whether to check
automatically or only when you click the link.

Other reasons to do it are that the manual can provide
additional context, links, etc.  It's not only about
more details about the thing described in *Help*.

No need?  Can't argue about need.  But a link is more
obvious than knowing, or checking to find, binding `i'.
IOW, need or no need, a link to the manuals is useful.
