Try really hard to fathom why OP would advocate easily breakable NPM/yarn clutter to an otherwise (and admittedly well designed long-standing) solution by ssh `config` and `-i` flag -- if at all not built by other language base e.g C++ Java If there is a need to use separate identities, without trying to be pedantic, simplest means is via understanding the ssh tooling in POSIX compliant systems. Thinking of solving this everyday operational problem with JS/TS packaging is inventing a new operational problem. NPM might be great for desktop & web application dev, but I wouldn't consider the stability as rock solid - something I will trust my system tasks with.
