More powerful than what?

Rather than thinking in terms of alloc/free it might be helpful 
to think about it more generally as resources, use, reuse and 
side-effects. On the stack you get to reuse memory when the 
variable is not longer live, meaning you junk writes if the 
results cannot be read and reuse the memory "prematurely".

If you are saying that turning GC allocations automatically into 
stack allocations is a good direction for D2, then I agree.
