- current maintainers and those who are on supported architectures can use the Rust implementation. The current maintainers no longer want to maintain the C implementation and that is their prerogative as this article describes.
- new maintainers and those on unsupported architectures can continue to use the C implementation. Not everyone in the current user base (to include some distribution maintainers) is able to use the new Rust implementation at this time, but they still need the library.
It's not ideal, but it seems like the only practical way ahead that meets everyone's needs.
