Rule proposal: Don't pass default values to functions

Fail

function run(always = true) {}
run(true); // Error

function run({always} = {always: true}) {}
run({always: true}); // Error

function run({always = true} = {}) {}
run({always: true}); // Error

function run(options) {
	options = {
		always: true,
		...options
	}
}
run({always: true}); // Error

function run(options) {
	options = Object.assign({
		always: true
	}, options);
}
run({always: true}); // Error

And any other common defaults pattern (unless already blocked by other rules like prefer-object-spread)

Pass

run(); // No parameter set

Exclude

If run depends on arity/arguments.length

I never mentioned pay. It’s all about exposure.
