I am at a complete loss how this is any different or harder than shipping hundreds of bits of firmware or hundreds of quirks for random hardware (have you seen the entirety of the quirks tables in the Linux kernel) all based off hundreds of drivers shipped with the kernel.
You maintain profiles in a repo and package them like anything else. No one has indicated how this cannot usually be zero config via hardware probing.
You have to actually measure a profile to ship it.
That means sitting down in front of every single model with decent measurement equipment and running a test. This doesn't scale, especially not for a distro with limited resources.
Huh? Distros don't produce the overwhelming majority of the software or configuration they ship. There's no reason individual distros need to be part of this effort.
This can scale with a central repository that any organization including manufacturers or suitably equipped individuals can contribute to. It just needs to be permissively licensed. The major distros or associated vendors such as Redhat or Ubuntu certainly have the resources to host such a thing and so does the Linux Foundation.
