Thanks for asking. We don't plan on supporting it. The main reasons are two-fold. The first is that we don't want to confuse the market and consumers by allowing too many choices and so we decided on QR Code. The Second, and more important reason is that QR Code is by far the most prevalent type being used and AFAIK there isn't a scanner out there that only supports Data Matrix and not QR Code. QR Code also has better error correction capabilities which is important for things in the wild.
