Most people still use USB-A accessories.

Mice and keyboards work perfectly well on a USB-A connection, there is really no need to force everyone to buy dongles or to upgrade all your peripherals to USB-C.
In fact there is some parallel here; we all know that USB-C is the way of the future. Every phone, every laptop, every desktop will eventually have these ports for everything. It will replace every proprietary DC power plug. But right now, just like it was in 1998, the future isn't quite here yet.
And that was just one model, the Air. If you wanted an optical drive you could buy a white macbook or a MBP. Now there are no options.
