So what? The drive that is not in the quirks won't work anyway, so that 
if by auto-detection you can make at least fraction of those drivers 
working out of the box it would be an improvement. I wonder how other 
operating systems (Windows, Linux) cope with this issue. Not sure about 
a Linux, but I really doubt Windows has anything like our quirks, yet 
all drives work with it.
