Can you use custom allocators for all policies? If so, then the behavior of the behavior of the "onstack" policy could be achieved by using a stack-based allocator, like the one from Howard, right?

I think it is very elegant if one can switch to a stack-based version without huge code-refactoring if the performance need arises (I am paraphrasing your documentation).
