What rule do you want to change?

func-style

What change do you want to make?

Generate fewer warnings

How do you think the change should be implemented?

A new default behavior

Example code

/* eslint func-style: "error" */

// func-style report: Expected a function expression.
function noOverloads() {}

// No func-style report
function hasOverloads(value: string): string
function hasOverloads(value: number): number
function hasOverloads(value: unknown) {
  return value;
}

What does the rule currently do for this code?

Expected a function expression. 9:1 - 11:2

What will the rule do after it's changed?

Not report on the function declaration.

Additional comments

Quoting #19719 (comment):

I would take JoshuaKGoldberg's suggestion a step further and always allow overloaded function declarations. Don’t even add the option to report it. Otherwise it’s simply a TypeScript error.

Playground

function hasOverloads(value: string): string
function hasOverloads(value: number): number
var hasOverloads = function(value: unknown) {
  return value;
}

If there’s user demand, there could be a rule to disallow TypeScript function overloads. But IMO that feels out of scope for func-style.
