Updating fwupdate script it's officially updating the STM32 firmware all
on it's own!!! It flashes pretty quickly too. The STlink takes about 8sec to erase and write. I'm guessing it's erasing the whole 128KByte though. My own fwupdater takes ~3sec to flash, ~1.5sec to erase. So there might not even be that much room for speed up. 3sec is hard to beat signficantly anyway and it comes at the cost of bytes. Perhaps even complexity and risk of OUT packet errors/loss on the device side. So kinda like leaving it as is.
