OS Recovery
Code found in the iOS 13.4 betas reveals that Apple may also be taking the next big step to untether the iPhone and iPad from the Mac, with a new over-the-air recovery mode that would allow devices to be fully restored from the cloud, in much the way that you’ve long been able to for Macs.
While it’s already been possible for a few years to install iOS (and iPadOS) updates over-the-air, and of course you can wipe an iPhone or iPad and start over, if you found that things were really messed up to the point of requiring a reinstall of iOS, you were forced to turn to a Mac (or PC) and plug it over USB to reload iOS/iPadOS.
