An assumption, but it seems to me and many others that they’ve been slowly moving to make macOS more touch interface friendly.

I’m typically anti-touch screen on laptops as it drives the price up for a feature I personally almost never use, but there’s so many use cases particularly for a large portion of Apple’s user base working with digital media.

Aside: A Lenovo Yoga -like MacBook would be cool, although I do like the Touch Bar for quickly moving around in media I’m listening to in the background (but I don’t think that’s enough to justify it).
