Yeah fully agree, ECS is the microservices of gamedev these days.
I've worked on AAA games that used it, and shipped games as a solo dev without it. If you don't know why you need it, then chances are you don't need it. Just keep it in mind as one possible architecture pattern for when your code base starts to experience growing pains is my advice.
