Seems counterintuitive to me. Is there a rationale? How does this help
you think about things?

I used to have to integrate web video players with editorially
specified placeholder images. Using CSS background images instead of
<img> would have been an unwelcome conflation of content and skinning
which need to be kept distinct to allow restyling.

The idea that background images in the styling layer need text
alternatives suggests to me that there is functionality missing in the
content layer that discourages separation of concerns. Maybe the
discussion about responsive images, which are easier to specify in CSS
than HTML, is relevant here.
