'Log in with github' requests unnecessary write access

[kolen]

Write access is unnecessary when using github only as authentication service:

Actually, Crafting Guide uses GitHub as much more than an authentication service. When users edit wiki pages, their changes are saved as commits to the related documents in the crafting-guide-data repository. To add grant wiki editors contributor status (a necessary precondition to submitting a commit), Crafting Guide has to ask for this permission. Be assured, though... it only ever requests data related to its own operation!

Never going to happen:

This application will be able to read and write all public repository data. This includes the following:

• Code
• Issues
• Pull requests
• Wikis
• Settings
• Webhooks and services
• Deploy keys

You are dreaming, make a seperate auth section for that if you want that kind of access.
