From Six Colors:

    One major advantage of this, as Gurman says, is that it would
    potentially help breathe new life into the Mac App Store, which has
    never seen quite the same level of success as its iOS counterpart.
    Developers would still have to deploy a custom Mac UI optimized for
    trackpad and keyboard rather than iOS's direct touch interaction,
    but much of the code could then be written once for both iOS and Mac
    apps.

    Of course-and here I'm diverging into my own speculation-if Apple
    decided it wanted to create a direct-touch interface on the Mac,
    this would help that along as well. If apps already contain UIs that
    are optimized for touch, that could make it easier to bring touch
    capabilities to the rest of the Mac. It would still require some
    pretty large shakeups to adapt the rest of the macOS to a touch
    interface, but it could point the way towards [1]a future unified
    platform.

  [2]One App platform to rule them all

  While this speculation may come to pass, my hope is that it encourages
  developers to improve (and in some cases implement) better keyboard
  support in apps.

  If this helps Apple come up with pointing device support like the
  trackpad (or mouse), that would be huge for professionals. I think this
  is a highly unlikely outcome, but one can hope.
