This. I lay that split templates blame squarely on the WP default themes, something they began with TwentyTwelve, I think.

I took over a Drupal-WP conversion project, where the previous dev tried to build a duplicate of the Drupal site's theme using TwentyTwelve as a base, and the vast number of split templates he ended up using made me ill, and the mess he made of the CSS file was epic. The problem was the guy seemed to be a pretty decent PHP coder, but he knew zip about WordPress... something that I seem to be running across more and more and I haven't the faintest idea why.
