PC monitors don’t lack width, these changes ate just blindly applying mobile trends to desktop while disregarding their differences.

Theres is much innovation to be done in desktop UI design, but blindly following mobile is not the way. Mobile screens are usually smaller and have the opposite high:width rate, and you use touch vs mouse+kb. Different design patterns should apply.

Removing scroll on mobile makes sense, few usage on a very limited width. On desktop width is a commodity that is mostly left unused.

My XPS might as well not because they're placed horribly, MacBooks don't, and my Chromebook doesn't have the physical keys but maps them to hotkeys that some applications use so the behavior is inconsistent. My tablet and smartphone keyboards also don't have a way to send home/end with their native keyboards.
