Not necessarily. The vast majority of USB devices are still USB-A. Many people and many corporations still have over 25 years worth of literally billions of USB-A devices to support. With USB-A, you at least maintain port compatibility for all these devices. With USB-C, not so much with a cumbersome adapter (also representing an investment) being required.
Ideally, having both types of ports and multiple ones of each type would be the way to go, and only tablet in the world can lay claim to that accomplishment.
