[Rust] What to do with Rust packaging in EPEL9?

Seems rust-srpm-macros and rust-packaging are in the RHEL9 which means it is not possible to get them in EPEL9. That also means, they are already outdated and do not support our latest greatest consistent packaging across Fedora versions… Right now, I suppose it is still possible to get that stuff updated in the Stream9, but later on it will be harder and harder I suppose. So what should one do if they want up2date stuff through the whole EPEL9 lifetime?
