Rust 1.89 is now released, expanding x86 and x86/x86_64 platform support with new processor instructions and features, including additional AVX-512 intrinsics. The target_feature attribute adds support for SHA512, SM3, SM4, KL, and WIDEKL, giving developers better access to modern CPU capabilities directly from Rust code.

Seems to be justification according to their changelog. (Wish the site would just link to that) I'm assuming they were going to do it, anyway, now that Apple has pretty much phased out x86 support, and Github's discontinuation was just kinda put the final nail in the coffin.

    Yeah, feels a little bit early when I know some devs in my company that still have x86 Macbooks, but I guess, it's not like bugs will show up immediately, so we'll see how that goes...
