Yes, you can still find convertible disc hubs but the QR and narrow width are going to be increasingly marginalized. If you are starting from a clean slate, thru axle is the best choice. IMO, the primary advantage with TA and discs is that you get consistent fit when you remove/replace the front wheel. When you are dealing with a mm or two differentiating a chirping brake from a quiet ride, the QR introduces an unwelcome variable.
