What do you mean by "works"?

All that does is cause file bar-pkg.el[c] to be loaded
whenever someone or something tries to invoke/use function,
macro, or keymap `foo-fn'.  (But it does nothing if `foo-fn'
is a function already defined.)

Yes, nothing implies that `foo-fn' is defined in bar-pkg.el.

What doesn't have to be what way?

The right thing being ___?  I guess you wanted Emacs to
load that file when that function is invoked?
