I still don't understand what is the concern you are referring to.

If you have a concern, then it is because you think of a negative
situation in the future, no? So what is that situation? i.e. what is
the issue?

And, yes, quite a few people have asked about implementing a core
subsystem in Rust over the years. If it cannot be an optional
subsystem, then one will need to wait, or convince everyone else to
change the kernel policies, or convince major distributions to
backport the toolchain, or similar.

It is what it is -- after all, the point of the exercise was to take
advantage of the features from a new technology. But I don't see what
the concern is.

In any case, that discussion seems orthogonal to the allocators one.
