airbnb javascript estilo flecha-cuerpo-estilo regla, ¿por qué paréntesis sin llaves?

De acuerdo con la Guía de estilo de Javascript de Airbnb , se debe agregar un par de paréntesis para envolver las llaves. ¿Pero por qué?

 // good [1, 2, 3].map((number, index) => ({ [index]: number, }));

¿Hay algo malo si codifico sin esos paréntesis? Me refiero a simplemente devolver el objeto es más fácil de leer.

 // anything wrong with this? [1, 2, 3].map((number, index) => { return {[index]: number}; });
