I agree actually. But sometimes is it hard to articulate 'good reasons' 
for a principle based on the integration of over a decade of experience. 
I was really trying to point to the difference between

'I will not accept the experience-based advice until enough good reasons 
are presented.' and

'I will provisionally accept the advice but I would still like to know why.'

Another principle similar to 'Don't add extraneous code' is 'Don't 
rebind builtins*'. I have a separate post for that.
