Unless Linux is the default, it will never become significant in the mainstream. It is however thanks to improvements like these that OEMs can consider selling it pre-installed
Also I would to remind some here that the reason Linux can exist on the desktop today is because it is a very good way for Microsoft to get less antitrust fines. Otherwise the bootloaders would all be locked and there would be one or two devices that are unlocked.
This is also my main concern about the Qualcomm elite x: everybody is saying "hurray it will support Linux" but the actual cpu support was never really the issue. It's the boot process and device trees that is problematic and I don't see this being talked about enough. If it does not adhere to a standard device detection process like with Acpi via Arm System Ready we are cooked for arm laptops.
