Hay una gran posibilidad de que la lógica para tu *startup* y *shutdown* esté conectada, podrías querer iniciar algo y luego finalizarlo, adquirir un recurso y luego liberarlo, etc.

Hacer eso en funciones separadas que no comparten lógica o variables juntas es más difícil ya que necesitarías almacenar valores en variables globales o trucos similares.

Debido a eso, ahora se recomienda en su lugar usar el `lifespan` como se explicó arriba.
