Why does the factory reset actually delete everything - also applied updates - and restore the phone to the SailfishOS version This seems rather useless process, as the later OS versions were already installed.

The already installed version should always apply after factory reset, not the one that was "hard flashed" to the device (why isn't these updates flashed to ROM?)

As additional question, does every single phone component get reset to the initial state, or there is some part, maybe stuff under the SailfishOS level like e.g. the baseband firmware that doesn't revert back to its original version?

It truly is a factory reset, thus restores the phone to the state it left Jolla. This ensures that none of the possibly broken updates make the phone unusable for/unsavable by the user.

It also has to do the way it is done: Jolla uses btrfs as file system, which allows to make snapshots and roll back to a certain snapshot. And the "first" snapshot is done after the base system is installed. A factory reset rolls back to that first snapshot.
