The respective log entry is:

Submitted by Juergen Weigert:
patch #7056: adding support for mikrokopter bootloader to butterfly
* butterfly.c: Add some specific logic to handle the
mikrokopter.de butterfly bootloader.
* butterfly.h: Add one related function declaration.
* config_gram.y: Add butterfly_mk keyword.
* lexer.l: (Ditto.)
* avrdude.conf.in: Add entry for butterfly_mk.

So the submitter of the patch is probably the person to ask.  The idea
is probably that only the Mikrokopter responds to this, while it
doesn't harm for anything else.
