Hi Stephen / Piotr
Thanks for the explanations. Now its clear, I understand that both features are tightly related to allow the USB plugged in to PC and still let the payload code execute. Fair enough.
I have made a fork of luftboot to add gateway features and the 8K memory space of luftboot has become tight quickly. So I had to lean out the startup condition check as I wrote in my first mail. I have also deleted the flashing of option registers for similar reasons (ran out of space, did not find the rationale, fundamental functionality still works without it).

Karoly, also, there is an extra feature to check for some internal registers so one can jump into bootloader mode from the application payload through a reset. It is kind of a hack but not bad. Probably better to use BKP domain registers...
Having the bootloader disable jumper is rather useful in bench testing, as Piotr mentioned.
