Well yes, I do agree with this. Internally it's mostly consistent, at least more so than Windows. Never analysed its UI structures though.

As a platform, ensuring applications running on top of it stay consistent to varying degree is the job of the desktop/OS IMO. To what degree depends on the context, https://asktog.com/atc/principles-of-interaction-design/#con... is a great read.

Even games need it, missing input field features has plagued PC games for decades and can be crippling for input method users, Skyrim's console needs mods to support copy and paste. Custom mouse acceleration curves is the reason everyone disabled it, zero acceleration is the easiest way to make different games handle mouse input consistently.

A shame Linux isn't standardised enough.
