What are the plans for which 
seems to be still open?

Quoting form the ticket ...
Just to spam a little more, it seems that the HEAD happily duplicates all 
computations on unboxed types. It even duplicates x+x in this example:

foo :: Float -> Float
foo x = let y = x+x in y+yI haven't tested but this looks bad for 
performance critical code.
