Seems like they could just lock all of the new features behind a “use x.x” line rather than going feature-by-feature. And they could include “use latest” or similar for people who don’t care about the risk and are fine just fixing things if they break.

No, that is what they are doing. "use v7;" gets you all the new stuff and that will continue going forward. They only listed what "use v7;" is the equivalent of in the article.
