It may be an unintentional side effect, but doing this may prevent some degree of "Win rot", which Macos (and iOS) has also suffered from to a degree in the past. A huge number of mysterious iOS and Macos problems are caused by an accumulation of issues when config files of various types are "upgraded" along with the OS from one version to the next. If you look at all of the minor and major versions that come out in a year, small issues become large issues after being compounded by a couple of dozen updates. There was an issue with iOS a few years ago that caused higher than normal battery drain when I was managing a department that supported a lot of iOS devices. A lot of users thought they needed a new battery. The battery drain issue was resolved for 100% of our users by doing an "Erase all data" and NOT restoring the backup. This process will still fix an amazing number of weird iOS issues in 2021, especially issues with the device slowing down, getting hot, or draining battery. It works because you end up with default config files that were designed for that version of the OS. If you restore the backup, often it will "restore" the problem you were trying to fix because the iOS restore process puts some OS config files back. It will be interesting to see if Macos becomes less susceptible to win-rot type issues because of this config file reset behavior, as annoying as it may seem.
