   I agree,

   In the meanwhile you can add an

   mpconfigvariant_FLASH_16M_SPIRAM_OCT.cmake

   set(IDF_TARGET esp32s3)
   
   set(SDKCONFIG_DEFAULTS
        boards/sdkconfig.base
        ${SDKCONFIG_IDF_VERSION_SPECIFIC}
        boards/sdkconfig.usb
        boards/sdkconfig.ble
        boards/sdkconfig.spiram_sx
        boards/ESP32_GENERIC_S3/sdkconfig.board
    )
   
   if(MICROPY_BOARD_VARIANT STREQUAL "SPIRAM_OCT")
        set(SDKCONFIG_DEFAULTS
            ${SDKCONFIG_DEFAULTS}
            boards/sdkconfig.240mhz
            boards/sdkconfig.spiram_oct
        )
   
        list(APPEND MICROPY_DEF_BOARD
            MICROPY_HW_BOARD_NAME="Generic ESP32S3 module with Octal-SPIRAM"
        )
   endif()
   
   if(MICROPY_BOARD_VARIANT STREQUAL "FLASH_4M")
        set(SDKCONFIG_DEFAULTS
            ${SDKCONFIG_DEFAULTS}
            boards/ESP32_GENERIC_S3/sdkconfig.flash_4m
        )
   endif()
   
   if(MICROPY_BOARD_VARIANT STREQUAL "FLASH_16M_SPIRAM_OCT")
        set(SDKCONFIG_DEFAULTS
            ${SDKCONFIG_DEFAULTS}
            boards/sdkconfig.240mhz
            boards/sdkconfig.spiram_oct
            boards/ESP32_GENERIC_S3/sdkconfig.flash_16m
        )
   
        list(APPEND MICROPY_DEF_BOARD
            MICROPY_HW_BOARD_NAME="ESP32S3 microcontroller with 16MB of Flash & Octal-SPIRAM"
        )
   endif()
   

   along with

   sdkconfig.flash_16m

   CONFIG_ESPTOOLPY_FLASHSIZE_4MB=
   CONFIG_ESPTOOLPY_FLASHSIZE_8MB=
   CONFIG_ESPTOOLPY_FLASHSIZE_16MB=y
   CONFIG_PARTITION_TABLE_CUSTOM_FILENAME="partitions-16MiB.csv"
   

   and compile with

   make BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=FLASH_16M_SPIRAM_OCT

   This is a Micropython request, I might support, however, I also believe that generic S3 micropython support should be working for your board with a minimal setup.
