So if the information provided through the driver is too generic then we should ideally be fixing those drivers/systems to do something sensible. For the DT systems the generic cards have properties that let the system just specify names directly so it will just be a case of setting them properly and it should just be the x86 systems that are a problem. ACPI is a bit of a lost cause here, most of the systems aren't interested in supporting Linux in the first place and the idioms there aren't great, but for DT it's reasonably tractable to push back on people if there's issues and it's much more scalable to do that than telling individual users to do that.
DT works only partially. Also, you need the DT compiler to change something, it's easier to overwrite things in the booted system. The user experience is lower with DT.
TBH I think the ship sailed on user experience no matter what we do here :) In any case no disagreement that it's useful to have some way to do this at runtime for systems where it's not possible to update the firmware for whatever reason.
