ASCE 7 is not a materials design code. It is agnostic regarding definitions of things like "failure."

It is a code that defines the criteria for estimating or approximating design-level loads. The changes incorporate the progression of understanding of the loading phenomenon. 

For example, there has been a lot of research into the nature of how wind interacts with the surfaces of bodies to generate loads on those surfaces. ASCE 7-10 incorporates the more recent understanding. 

EDITORIAL NOTE: I have always been somewhat at a loss to explain why so many of my colleagues resist and are quite frankly militant against changes to the way things are done. 

I suppose you could use the old ANSI A58.1 code for loading if it makes you feel more long as "nothing bad happens."

And I guess you could insist on having all your kids' tonsils removed as well.

1.  How many of the changes are due to actual failures in the field of
structures properly designed by previous editions?
