If you maintain a @nodejs.org application that hasn't been updated for a couple of years, consider looking into replacing some userland dependencies with built-ins that are now available

Landed support for proxies in Node.js http/https builtins github.com/nodejs/node/...
To enable proxies configured from *_PROXY env vars: use NODE_USE_ENV_PROXY=1.
This was already implemented for fetch and released in 24 github.com/nodejs/node/... - soon the old builtins will also support it.

This patch implements proxy support for HTTP and HTTPS clients and
agents in the http and https built-ins`. When NODE_USE_ENV_PROXY

Remove dependence on `__builtin_*_overflow` builtins in generated C · Issue #138 · ashn-dot-dev/sunder
Currently, addition, subtraction, and multiplication rely on the GCC/Clang builtins __builtin_add_overflow, __builtin_sub_overflow, __builtin_mul_overflow. Replace these builtins with an strictly s...

you can overload some nix builtins.
e.g. `let __sub = x: y: x + y`
Now your builtins.sub will add
e.g. `let __sub = x: y: x + y`
Now your builtins.sub will add
quote this with a fact you know?
