It appears that some vendors provision the boot areas with valid part tables (GPT) in order to have identifiable partitions for device and firmware specific data, such has the qualcomm CDT (Qualcomm Config Data Table). Additionally, these boot areas can be utilized to host device-specific IDs, calibration data, and other critical information.
