I've been interested in creating a policy-based framework to handle
stack-only allocation, SBO, allocators and the never-empty guarantee for
a while, but I haven't found the time to do so yet.

All single object containers could use that, so it's best to factorize
in my opinion.

Of course, any can be empty, so stack allocation is not such a problem.
