I can tell you that devices with Apple CPUs _do_ have multiple NVMe namespaces. The recovery OS and 1TR are not data needed to be saved permanently (as in serial number and such, without which you cannot restore the device), you can recover them through DFU. Data critical for being able to restore is in the SPI flash. (and it's assumed that some of it might be in other NVMe namespaces too)
