A benefit of targeting Boost is that a library can experiment with
making such decisions without etching it in stone (as would happen if
it was a Standard C++ component). For example as I have done with
Boost.JSON, which provides a novel "storage_ptr": a smart pointer
container to a reference-counted memory_resource, and has some
opinions on exactly how it is propagated to children:
