Node v8.x not allowed due to devEngines setting in package.json

What is the current behavior?
Currently, only the following Node versions are allowed because of the devEngines value in the package.json when executing npm install or any other script: "node": "4.x || 5.x || 6.x || 7.x".

Error:
Current node version is not supported for development, expected "8.0.0" to satisfy "4.x || 5.x || 6.x || 7.x".

What is the expected behavior?
Unless there is a reason for not allowing version 8 yet, could we update this?
