If we've learned anything from the history of CSS, JS and the semantic web it is that 99% of the time a feature will be used in ways that were not intended. There is no reason to suppose that this will be any different.
You have to consider why, and the answer was often "there's no other way".
The paths of least resistance on the web are now very different. These features were not delayed due to implementation details, but a deliberate shepherding of the standards. The most powerful features were saved for later and even still this is scoped to media queries, etc. only.
