This gets pointed out by somebody in the comment section under every Rust update. The trope that Rust is getting harder to use is tired, and not really based in reality.
And while its fine for high level scripting languages like Python, because the whole idea is to abstract a lot of the functionality into the syntax, the issue with Rust is that its trying to be the next C and be applicable for writing critically important pieces of software like parts of the linux kernel. You absolutely must have a locked down language set for this. The reason C is still used for the kernel isn't because of circumstances, its specifically because there is very few ambiguities in the core language.
Which of the features in Rust 1.63 adds a divergent way of doing something you could already do?

What are some ambiguities in the core Rust language?
You don't need a "locked down" language to build an OS. In fact Linux just upgraded the version of C they use to C11. Time always marches forward, my friend.
