Indeed, but even in the case of pure register dumps, there is no way the
actual firmware blob in the current kernel constitutes "the preferred form of
modification". That said, it is my experience that more often than not, those
firmware blobs are indeed code, especially when one talks about a device with
an embedded mips core for example.
We could try to do a determination firmware by firmware, depending on its size
and stuff like that, but we are particularly trying to postpone this work

The ftp-master position has always been one of erring on the side of caution
