Rust has been really great at incremental language upgrades because of clippy. Stuff get deprecated, clippy issues warnings, buy the time support is dropped your code has been patched.

It feels like we are in some new weird software engineering world where the code is only alive while its actively maintained and worked on. The libraries that are shipped in the OS seem as constant and fixed in time as x86, basically completely abstracted by the constantly evolving software on top of it.
