[Proposal] Service Provider Routes Function (cosmetics)

[ghost]

Simply cosmetics for package developers.

Add function to \Illuminate\Support\ServiceProvider.

/**
 * Register routes.
 *
 * @param  string  $path
 * @return void
 */
protected function loadRoutesFrom($path)
{
    if (!$this->app->routesAreCached()) {
        require $path;
    }
}

Allows the developers boot() function....

/**
 * Perform post-registration booting of services.
 *
 * @return void
 */
public function boot()
{
    $this->loadRoutesFrom(__DIR__.'/../routes.php');

    $this->loadMigrationsFrom(__DIR__.'/../migrations');

    $this->loadViewsFrom(__DIR__.'/../views', 'package');

    $this->publishes([
        __DIR__.'/../config.php' => config_path('package.php')
    ]);
}
