I am not sure whether it works, but at least it builds on aarch64:
   https://ci.guix.gnu.org/build/37421/details
This is rust-1.60, our publicly visible version; internally we are at 1.65,
which I suppose the rust-team branch is going to make visible soon.
I also see a few green dots of rust-* packages in the dashboard, alongside
many red dots; a random sample of them shows they suffer from the infamous
cuirass bug "cannot build missing derivation".

So I think we are good as far as core-updates is concerned, and you can
make the changes on the rust-team branch when you see fit.
