Mostly that's true, but it's not really specific to things that are dumped. The issue applies to all variables/fns initialized by Emacs, but not to things that are autoloaded. Often, the set of all variables initialized is the same as the set of what is dumped into the Emacs executable. But, lets say your .emacs file loads foo.el, or triggers the loading of foo.el by using an autoloaded function or causing an autoloaded function to be loaded indirectly through some other function. If this happens and you replace foo.el with another library later then the issue may occur. None of this is a big problem of-course.
