I have contacted Avik De who runs Koduino and he is very interested in the new STM core, so I would wait and see what STM release, later this week.
Koduino is good for STM32F405, I have use it to programm my new board - blink a LED.
But I use USART to download the program, need to press the BOOT0 pin to high and Reset. It's not convenient. Of course, I can use a USB2UART chip, two transistors to replace the buttons. But more components is needed.
STM32F405 supports DFU mode. It looks like Koduino doesn't support it now. need a tool DFU_UTIL.
I think Maple's mode is better. Only a USB support programming and VCP.
