There are apps, like WhatsApp on iOS, that receive silent notifications and are started upon receiving them, allowing them to process these notifications locally (as explained in my other comment in this thread).

This method enables them to bypass the need for sending clear text content through Apple's servers, upholding their end-to-end encryption.

However, this practice can slightly impact battery consumption, which is probably why this specific entitlement is not freely available to all apps. It's a balance between enhanced security and a marginal increase in battery usage.
