>Currently it is still adding :leave and --reset for all boards without explanation.

Wasn't this an explanation?
>Actually I think they're a bit redundant, but it doesn't hurt. :leave after the address will just tell the bootloader to leave DFU mode after flashing, which doesn't mean it will reboot the device. On the other hand, --reset indeed reboots the device, which by definition will exit the DFU mode.

>I researched a bit to try to find where it was coming from and it looks like it is an stm32 only thing for dfu

I'm not pretty sure, DFU is supposed to be an standard, used primarily to flash BIOS-like things for linux machines. It's even present in some other devices like webcams.

>If everything works with only --reset and it is the most general thing, maybe go only for this one.

It's hard to say if it's the most "general" thing. IMHO both don't hurt and can co-exist, thus ensuring a correct DFU mode exit and board reset.
