Except that it is likely to be included in future versions of Fedora:

According to the official Fedora change proposal, the rewrite expands support for both bootc and rpm-ostree based systems, whereas the original Bash version was built only for rpm-ostree. Red Hat developers have submitted a proposal to ship this new Rust version in Fedora 43. According to Phoronix, while the plan still needs a final vote from the Fedora Engineering and Steering Committee, it looks very likely to be approved. For current Fedora IoT users, the change promises to be a simple, seamless upgrade.
