Most developers should never need to touch or swap out allocators.
It can be a performance optimization for the more advanced users.

Let container makers decide a good default for /their/ implementation.

Allocators solve a problem that very few developers actually have. 
Contrary to popular belief. The default GC allocator is probably ok for 
most people. I'm happy with it for SPEW[0] and it heavily uses allocators.
