I thought how commands are bundled into packages was the entirety of what we were discussing. That was my interpretation of larkinrichards's comment (way) up above. Packages are the unit of installation, not use. Packages are all we're arguing about.
My position: don't put words in God's mouth :) The unix way is commands that do one thing and do it well. But the unix way is silent on the right way to disseminate said commands. There you're on your own.
I support packages of utility functions. Distributing them individually is a waste of resources when you have tree shaking.
I trust a dependency on lodash. I don't trust a dependency on a single 17 line function.
