Research done by MS and the accessibility community found that a single description field, without a title field, is easier and less confusing for both the author and screen reader users consuming the content. Accordingly, MS changed the interface to enable people to author accessible documents, and enable people to understand documents they're consuming using the accessible technology of their choice.

Accordingly, I don't see MS reverting to the former setup. That said, you could lobby for a change on uservoice which is not solely for enhancements as you claim.
