I'd prefer we teach the Help facilities how to go to the source code of
that kind of functions. Some years ago, I added support for go to
definition from *Help* buffers when the symbol was generated by a Lisp
macro; there's no reason we couldn't extend the code to also handle this
particular case.
Showing the source code inline is something I feel more suitable for
third-party packages. It is probably more interesting from a core Emacs
perspective to make sure that help-mode provides the appropriate hooks
for users and packages to customize what to show without needing to
reimplement *Help* from scratch. I don't know what other people think,
my opinion about this may be a minority.
