This has been brought up for discussion more than once e.g.:
     https://public.kitware.com/Bug/view.php?id=15517
     https://public.kitware.com/Bug/view.php?id=15222
     http://public.kitware.com/pipermail/cmake/2016-April/063306.html

Personally I still don't think this needs change.
You don't have to browse all versions of the documentation ... you only 
have to work with the documentation that matches the version you 
declared in cmake_minimum_required().
