 - The ESP32 arduino/platformio project doesn't support the nice "if initVariant() is found, call that after init" behavior of the nrf52 builds (they use initVariant() internally).
 - Over the years a lot of 'board specific' init code has been added to init() in main.cpp. It would be great to have a general/clean mechanism to allow developers to specify board specific/unique code in a clean fashion without mucking in main.
 
-So we are borrowing the initVariant() ideas here (by using weak gcc references). You can now define lateInitVariant() if your board needs it.
+So we are borrowing the initVariant() ideas here (by using weak gcc references). You can now define earlyInitVariant() and lateInitVariant() if your board needs them. earlyInitVariant() runs at the beginning of setup() directly after waitUntilPowerLevelSafe(); while lateInitVariant() runs after the LoRa radio is initialized.
 
 If you'd like a board specific variant to be run, add the variant.cpp file to an appropriately named
 subdirectory and check for \_VARIANT_boardname in the cpp file (so that your code is only built for your board).
