I think for the JTAG ICE mkII code, we could even change AVRDUDE to
use "read signature" rather than "spi multi", because there are only
two clones I'm aware of (the Kee Electronics one, and an experimental
version of usbprog, but I'm not sure whether they even do implement
ISP at all), so there's little risk of breaking something else.

Anyway, as the STK500v2 implementation of the "read signature" command
is almost identical to using "read multi", there's no real advantage
anyway.  For sure, it would be good if Kee Electronics changed their
firmware for full compliance with the described protocol.

What's interesting with your observation is that obviously, Kee
Electronics really wrote a firmware version of their own.
