I think another great difference is that in your proposal a 
pointer has ownership of the memory but I think that structs 
should have ownership over resources and pointers are only 
borrows (like references in Rust), this way is more useful and 
lets you track ownership over other resources other than memory.

Another point is that on Timon's proposal scope pointers can be 
members of structs so you can have a safe slice that borrows from 
a container.
