Relatedly, if you aren't developing C/C++/Rust packages against Node's FFI (rather than emscripten and wasm these days), why do you need a version manager for Node at all, just use your preferred package manager and stick to auto-upgrades of Node LTS.

(That's one of the things I appreciate about Deno is the "let's just auto-install point upgrades" evergreen mentality and its suggestion that side-by-side versioning is maybe a mistake in the JS world.)

nvm added like 3+ seconds to my new shell startup, and one of the maintainers defended it with "so what, how often do you open new terminal windows?"

One thing I've learned about tech is that you can never assume something is too boring for opinions.
