@MattClark The issue you're likely to have is that even if you get the tag approved, each change you make will need to be reviewed and approved (I think by two people). The unit-testing proposal got committed to quite quickly (faster than I was expecting), but reviews aren't taking place.
If it's an area that you're committed to documenting when it becomes available, then preparing your examples in preparation for the public beta (when hopefully you'll get the committers) might be the way to give the area a jump start when it's ready.
@JonasCz If you could remove you're upvote, I would be interested to see the impact, thanks.
@JonasCz As far as the answer goes, the bit of the question I was responding to has been edited out. It was more of a critique of the question than an answer, so I'm not sure it really adds value at this point, which is why I deleted it.
