The second example isn't syntactically correct.  What are you getting at here?

FWIW, there was a proposal to add a package qualifier to import 
declarations, but it wasn't unanimously viewed as the right thing at the 
time (check the libraries at haskell.org archives).  Same goes for the various 
"grafting"/"mounting" proposals - we just haven't seen a proposal that has 
the right power to weight ratio.  Meanwhile, the current package system 
seems to be scaling quite nicely, thank you.

We do intend, I think, to allow packages to re-export modules, it just 
needs to be implemented.  (I see it as a missing feature, rather than a bug 
or a "design flaw", though).

Cheers,
