While that is by far the most widespread system thanks to GNU/Linux, it is not the only one. Emacs uses a very similar scheme, but treats 1.0alpha < 1.0beta < 1.0pre < 1.0 == 1.0.0 == 1.0.0.0 which sort of makes sense, but can't be handled by a simple lexicographical sort. You also have to be able to ignore non-sortable components like Git commits. All of this is already existing in Cygwin, so unless you're proposing that these version numbers should all be changed to conform to the one true version scheme (which will be painful in other ways), then I still propose that we need to make the version ordering switchable.
