I'm not sure this actually improves the flow for me. I (like most sane devs), like to lock my deps to specific versions (or vendor them). Currently, it's just a matter of running:

npm install --save dep

With this, I either have to be satisfied with not locking down the version, or go lookup the current version manually before adding the reference to my code.

It also looks like upgrading a dep would mean changing every require.
