why must create project first, then can get the version info

--version is so common usage, why change it to just version

why not using -v, but v, very confused me ❓

$ ng --help
$ ng -h
# $ ng help

# must create project first, then can get the version info
$ ng new angular-fullstack-app

# $ ng --version
$ ng version
$ ng v

➜  angular-fullstack-app git:(master) ✗ ng v
