We are discussing possible ways in order to make Code Review more useful for external users. Right now code is reviewed and that's it, the question/answer is no longer useful for anyone else. One of the ideas that popped up was to apply specific tags to questions in order to categorize them as examples of design principles or bad practices.
We were wondering whether it would be possible to use custom tags similar to moderator tags on meta for this. The system already implements something similar to allow some tags to be red. Obviously it would be more complicated than 'just moving the feature over to main', but it doesn't seem unfeasible, and it could be a nice feature across the network.
