Why does this module exist?

[christianbundy]

This feels like a very silly question, but why don't each of these module just encode their own defaults? The more time I spend thinking about this pattern, the more of an antipattern it feels like.

Current implementtion

const ssbConfig = () => ({
  foo: 42
});

const ssbFoo = (config) => {
  console.log(config.foo);
};

ssbFoo(ssbConfig());

"Proposal"

const ssbFoo = (config) => {
  if (config.foo === undefined) {
    config.foo = 42;
  }
  console.log(config.foo);
}

ssbFoo();

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
