It would be more flexible.  Instead of having to actually replace data 
with NaN, you could create a mask which marked data to be ignored for 
the moment:  all negative values, say, or all values with a complex part 
less than 1e-5.  Much more flexible.  Having said that, I agree that NaN 
should also be ignored wherever it occurs.

-1 on the kwarg.  It seems to me that adding it to every plot command 
uglifies the interface significantly as well as being more work for John.
