Thanks for the additional points! What you state is true, but somewhat orthogonal to the point that the grandparent post was making (and I sought to refute). C

Thanks for the additional points! What you state is true, but somewhat orthogonal to the point that the grandparent post was making (and I sought to refute). Creating an allocator is inherently possible. Using that allocator with the rest of the ecosystem is currently not stable, as you point out. As a sometimes Rust embedded developer, I look forward to both parameterized allocators and fallible allocation.
