Its not *that* dangerous, but you have to know what you are doing.

You cant downgrade firmware in a failsafe manner. But by failsafe we
mean "safe even if it fails". There's no reason for downgrade to
fail more frequently than an upgrade.

You should be fine as long as you burn with flint -nofs (nonfailsafe) and dont
reboot or kill or reset the chip or the burner otherwise while in the process
of burning.
And there's actually a pretty good chance you'll be able to resume even
if you do, so long as you dont try to load the driver.
