Even if they did, it would be out of date the moment it shipped.

But no, there's no reason to believe they'd do anything like that. It would be interesting if headphone manufacturers reported the dB range when connecting with Bluetooth to enable something like that, but I've never heard of such a thing. (That is an area where Bluetooth could enable something like that, in a way that the 3.5mm jack couldn't.)

Software updates aren't just for distributing first party malware, you know -- they could also conceivably be used to update a device database. We have the technology.

This is probably an "all of the above" situation. Implement on AirPods and push for a standard and make measurements of popular old models and have a fallback that assumes industry averages. On the scale of Apple, this is not much to ask.

Or, they could just make the volume slider run from min to max, instead of loud to louder.

Presumably the manufacturers already calibrated volume range based on the Bluetooth spec.
