I had similar thoughts when I read this, but I can also remember a bunch
of very overdesigned attempts to reorganize and structure the kernel
logging code. I lot of time was wasted in the past for things that
ended up being too invasive or inconsistent.

The other part I noticed about this particular patchset is that it's
not really "firmware" as such, but specifically PC wiht ACPI that
gets covered here. So rather than generalizing the code, another
option would be to narrow down the scope and make it
acpi_{warn,info,dbg} instead.
