More than anything this discussion (and the one about the image style features) brings up an important point about explaining what is going on and why it's happening. As with the image styles, there was no official announcement from the core team about this feature being removed nor an explanation of why. For the average end-user this is terrible because lack of info means they'll most likely think something a) is wrong with their site, or b) is wrong with WordPress.

As we move forward it is more and more important that changes like these are announced and explained to the end user in the same way that new features like emoji and Kickstarter support is announced.

This isn't a feature problem, it's a communication problem.
