Support for oscillator calibration in LUFA-powered AVR-ISP MkII clones?

[HwAoRrDk]

Does anyone know whether or not any version (or fork) of the LUFA AVR-ISP MkII firmware - as used by the vast majority of MkII clone programmers, including one I have - supports target device oscillator calibration routines (as described in app note AVR053)?

I was having a poke around in the LUFA GitHub repository, and I think I found the code that responds to programming protocol commands in V2Protocol.c, but it doesn't appear to handle CMD_OSCCAL, so I guess not?

Am I going to need to acquire a genuine Atmel AVR-ISP MkII if I want to do oscillator calibration?

(Yes, I am aware there are several ways of doing ghetto-ish calibration routines, but I was hoping for some method I could semi-automate for calibrating a whole bunch of chips.)
