I disagree (mostly just to be an @$$#%^!% and get a dig in on that  
gazillion lines of unsnipped material).

I would venture that if anything is written into the Code it should simply  
state performance requirements rather than specify particulars like eave  
depths which, as pointed out would be very site-specific.

I can think of situations where even ridiculously wide overhangs (ie  
exceeding 1.8 metres) still wouldn't provide sufficient protection.

And there are many situations where wide eaves would almost certainly  
guaranty that the roof would be ripped off by winds or invite destruction  
of the roof by wildfires.

I would venture that if something is written into the Code it should be  
something like:

"The building shall be provided with means to keep the wall materials dry  
or if allowed to get wet, the drying regime exceeds the wetting regime  
over any given period of ## days".
