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.)
