The backends should probably be refactored to be aes_backend first

There is a minor problem with aes_compact. To be consistent, aes_backend = "soft-compact" should mean that only the compact software backend is used, while users may want to have both auto-detection and a more compact software fallback.

There’s also AVX-512 which has one cfg to enable it, and another to force it

I consider the AVX-512 "enable" option to be experimental since we plan to remove it in the next patch release, so it can be kept as-is. But I guess we may have similar new backends in future.
