I would actually prefer this.

I understand the appeal, but the idea is for the quirks to be
very specific (hence they are enabled only if specific
drivers are compiled in) and not start to be helpful. Doing
this would make any vendor,foo start to work and I don't like that
at all: any such mechanism will invariably be abused.
