Well, I personally think a "yes" to the last question would be utter
madness.  Whoever answers that should better come up with an alternative
patch for sysfs support pronto.

Large flashes are not a one-off cases where a single manufacturer had a
rather bizarre design.  Their numbers will continually increase.  And
not supporting an ever-increasing class of hardware is simply not an
option.
