It might be useful to define HOW an interface could change but still work with older applications.

Eg: /proc/self/stat - new numbers are to be added to the end of the line.

This might seem natural, but for this to work applications need to be aware that this might happen -- ie ignore anything beyond what they expect.

This strategy will not always work, but it might help prolong the life of some interfaces, ie not break old code.
