What does this mean for enterprise distributions, like RHEL, which
need to maintain a stable kernel ABI as part of their business model.
I assume it means that they will need to lock down on a specific Rust
compiler and Rust libraries?  How painful will it be for them to get
security updates (or have to do backports of security bug fixes) for
7-10 years?
