My comment was to resolve your puzzled state about usefulness of the new
feature ;)

That would make sense. Yet, even without narrowing, I personally do not
like that the point moves from the defun I am working on to other
function definition.

Also, a subtle difference between showing the source code in help buffer
and jumping to the defun is how much text is shown. In the help buffer,
source code is effectively "narrowed" to defun - no surrounding code is
shown.
