Yes, of course. We will support this, but how exactly it will look
like, to what extent upstream Rust's `alloc` could support our use
cases, etc. has been on discussion for a long time.

For instance, see https://github.com/Rust-for-Linux/linux/pull/815 for
a potential extension trait approach with no allocator carried on the
type that Andreas wrote after a discussion in the last informal call:

    let a = Box::try_new_atomic(101)?;
