Rechecked on a K3 with v3.2.1 firmware.
Doesn't seem much use for anything other than hardware diagnostics. Unless you need to change your MAC address, PCB serial number, etc, etc.
I did not try the MoviNand entry because I did not know if it would be a destructive test. Will leave that one for someone else.
Note 1: It might be of use with K3's that have battery problems (or low charge) -
The battery management reporting shows the machine is in a 500ma recharge mode with an external power supply connected.
Note 2: There might be situations where this diags mode could export the user storage file system when the normal mode could not.
?? Hmm... How to make use of that? You need to put ENABLE_DIAGS on the exported file system to enter the hardware diagnostics. Still there might be some use for this.
