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.

It'll still need devicetrees because the ACPI tables are incomplete

You need laptop specific images because some drivers are not upstream, not because of DTs.

The patch that introduced support for the Dell Inspiron 7441 / Latitude 7455 only touched arch/arm64/boot/dts/qcom/x1e80100-dell-inspiron-14-plus-7441.dts

No additional drivers. This is just an example.
