Yes, but still this primitive method is a infinitely superior to the
technique Philips uses in its LPC devices.

Yes, this is for use in a laboratory environment where students have
no reason to load code that modifies flash.  The flash just contains
static library and OS kernel which never needs changing except for
infrequent updates.
