It's a good trend, in my opinion, and one I hope becomes the norm for MMOs.

It provides those who just want to see content, not necessarily cooperate with 9 or more other people in a raid environment, a way to do so without requiring the raid version of the content be nerfed to the lowest common denominator.

True raiders can have their challenging content, apt rewards, and be happy, and non-raiders can have an alternate means of experiencing the content and progressing their characters. Whiners who care only for loot and demand easy raids can go home. Everyone wins, yes?
