I'm currently working on one, will release the website this weekend and the first public in-development build next week. I'm combining the kernels and CPU-specific optimizations from CachyOS (compiled and hosted myself to be in line with their repo policy and licenses) combined with the way SteamOS makes Arch-Linux atomic/immutable, implemented a little more to the way Fedora Silverblue does it. So pretty much unbreakable PLUS fast and optimized.
