"Wrong" ML in camera - what happens?

[VisualPursuit]

Now with ML available in the nightlies for 5D mk3 running 1.2.3 I have been
musing over the following:

Since there is not yet a unified version covering both the 5D Mk2 and the
5D Mk3 I have to make sure to keep track of which card holds which version
of ML and in which camera to put it.

What happens if I screw up and put a card with ML for the 5D Mk2 into the
5D Mk3 or vice versa?

Sure, I could test. But maybe somebody has wise advice without the possible
risk of testing.

Thanks in advance.

NOTHING, it won't do anything at all, nothing.

I was similarly curious as I have a 6D and a 60D, so no problems if I put the wrong version in the wrong camera?!
