Without FCM, push notifications become much harder due to the battery saving optimizations each device manufacturer uses. So not a need per se, but it makes your life MUCH harder
Of course, an OEM may do aggressive app killing where the above may not work (Huawei is notorious for this), but that is an OEM-specific issue that applies to all apps in general, so as a developer it’s up to you whether you want to test against, or even support such OEMs.
