Interposition of non-static non-inline non-weak symbols is supported 
independend of if they are defined in the same TU or not (if you're 
producing a shared lib, that is).  I.e. no, they are not considered 
locally-binding (for instance, they aren't automatically inlined).

Because IMHO interposition is orthogonal to TU placement, and hence 
shouldn't be influenced by it.  There's visibility, inline hints or 
static-ness to achieve different effects.  (perhaps the real reason is: 
because it always worked like that :) )

Why?  I think it's right.
