That's interesting! Doesn't do much for debug, though. The bootloaders
I've written all take the hex file directly. Some take it as an HTTP post
where it's parsed to a binary image for the chip, saved in external flash,
then copied back to internal flash. Others accept the hex file over UART
or SPI, then parse and write directly to internal flash. This is great for
field updates, but, of course, does not support debug.
