Question about the status of <memory_resource> support


I was experimenting with std::pmr::vector and different memory resources, when I realized that libc++ doesn’t have the necessary header in version 8.

I have seen the series of pull requests by Arthur O’Dwyer:

As a clang and libc++ user, I would really appreciate the support for polymorphic allocators.
I was wondering if there is someone keeping an eye on these pull requests.
Or maybe someone else working on <memory_resource> support for libc++.

Thanks in advance,
Boris Staletic
