The question here is not whether the types exist, but which types are
the same as which other types.
I think that what you want is a model of visibility in which all types
are always visible. Although abstractly such a model is possible, I
think it's less useful than the current model, because it makes it
hard to isolate shared libraries from each other. It is certainly
possible to emulate such a model with the current GCC, if it's what
you want, by simply not marking types as hidden.
