Rust bindings reference non-existent "std" feature about blst

[dot-asm]

And the problem is...

But on a serious note, Cargo.toml is not the only way to engage a feature, and the referred line is a conscious choice in the context. If you want to complain that you can't control it, then you have to recognize that you couldn't do so in the previous version either. In other words, there are no observable changes for current users. That's the point. But there is new possibility to compile blst for bare-metal platforms for new users.

Sorry, I don't quite understand?
It's not possible to activate this feature when importing the crate as a dependency under other projects using Cargo, such as c-kzg-4844, because it is not declared in Cargo.toml, and for Cargo this means the feature does not exist. That cfg line can never be enabled from other Cargo projects.

Again, there are no observable changes for current users. In other words, if you had a reference to blst 0.3.10, then no modifications shall be needed upon update, new version shall keep working exactly as it was before. If you're disputing this assertion, then tell what is it that stopped working or changed behaviour.
