It makes sense for features like these to be not on GHE. But I am talking about features like new auth interface/webhooks etc which have been on github.com for more than half an year.

We made the unfortunate mistake of tying up too much of infrastructure to GHE and now are hostage to their whims. They give you back a canned response if you ask them about a missing feature in GHE through their support channel.

I guess it makes me mad that they are working on new features without fixing months old features which they consider to be unstable for GHE( if that is the case).

We were just discussing this yesterday -- there's a lot more focus on the UI than on the internals, and as john is talking about, they're not too focused on the UI for GHE vs GH proper.
