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.
