Can I ask what's the utility for this package?

Hello dear maintainers, I saw that this package is active and some blogs are talking about it but still not sure what's the advantage of it instead of doing the manual unsubscribe?

The main advantage is less code, I don't have to bring in ngOnDestroy in all my components, create another variable to hold the subscription. then unsubscribe and manage subscriptions.

I can just use the package.
