What is the status of nixos-infect? Is there an alternative project with the same scope?

I added a PR for nixos-infect that adds support for (at least some) RHEL-based distros. I noticed that there are quite a few stale PRs in the repo. Is nixos-infect known to be actively maintained or is there a similarly scoped project that is considered more appropriate for converting existing Linux servers to NixOS?

To be clear, I think nixos-infect has been great for my purpose, so no shade on the project!

I personally use nixos-anywhere, which is great as it integrates well with facter and disko.

I recently stumbled upon nixos-bite. It seems to only support Debian-based systems for now though.
