Spec says that volatile devices `may` implement an lsa.
Right you are.
Get LSA (Opcode 4102h) The Label Storage Area (LSA) shall be supported by a memory device that provides persistent memory capacity and may be supported by a device that provides only volatile memory capacity. The format of the LSA is specified in Section 9.13.2. The size of the Label Storage Area is retrieved from the Identify Memory Device command.
