Some years ago all hardware data was moved out of various separate
packages into the "hwdata" package (even if it meant moving it out of
the original upstream source).  The feature page doesn't even mention
the hwdata package.  AFAICS this

1) Duplicates the data.
  1a) Will the two databases be kept in sync?  How will that happen?
  1b) What is the long-term goal?  Will one of the two go away?  If
so, how and when?

2) Breaks the hwdata-vs-code separation that was created earlier.
What were the reasons of the separation, and why are they no longer
applicable now?
