Does this sound insane to anyone else?

EDIT: I understand not wanting to modify node's `require` semantics, but this is an unacceptable sacrifice of consistency for efficiency. Surely it would have been possible for an `npm install --save x` to put the `node_modules` directory in a state identical to `npm install --save x && rm -rf node_modules && npm install`. It might take a little longer to shuffle some directories around, but certainly not longer than a full `npm install`.
