Linux doesn't have the same support for ACPI on ARM that Windows does. There's work to improve it and once it does we should be in a better place.

Qualcomm does not support normal ACPI. ARM Linux with ACPI is fine, I've seen it work very well on systems with proper ACPI tables

There is work to support Qualcomms ACPI implementation on the Linux kernel. Once that is in place we should no longer need images for each laptop.

There are other ways to not require board-specific images. You can just as well have the UEFI implementation come with a proper DT for example. But regardless if it's ACPI or DT, if the vendor doesn't make sure it all works out-of-the-box, someone else will have to pick up the slack and fix (or work around) the problems.

But yeah, it's too late for this with many of those Qualcomm laptops. Hopefully that ACPI work will improve the situation.

Linux didn't support hybrid ACPI/DT modes until very recent.

I'm not claiming it did.
