After perusing through multiple forums and support pages, I haven’t found a single reason why paying customers are not allowed yet to restrict access to the documentation published to Github Pages. The lack of that feature makes the use of Github uncomfortable to some degree since we are left with only two options:
1- Wiki pages, for which you would need to create a separate repo and the wiki for the repo
2- Third-party solution
Is there a way to figure out whether the Github Team has considered providing this feature at some point in the (near, far, never) future?
