tried to edit it. but why would they mention it so prominently in the NOTAM?

  I'd say because aviation is risk averse and if a condition will impact a certain type or model of aircraft it is not going to be omitted (the fact that it's a smaller aircraft might imply in having some certification differences as well)

  Because it's still unexpected behavior, and suddenly losing aircraft systems mid-flight is a concerning event for a pilot. Especially ones related to flight control. That doesn't mean the plane can't fly. But it does mean that the pilot is going to have to fly it differently to avoid dutch roll, possibly flying at a lower altitude. Keep in mind that this is aviation, which is very risk averse (by necessity). Even minor issues are treated as significant.

  Because when this bug happens, the pilot is going to face a "christmas tree" of warning lights and cautions, most likely provoking an immediate PAN or Mayday and a possible diversion to the nearest suitable airport. Loss of attitude info is a serious business, in the worst case the pilot may be left to fly only "raw data" and using the backup "steam gauge" instruments, because the displays and automation will stop working. Such event is no cake on a big jet, even during daylight, perfect weather and with the crew perfectly current and capable to fly like that. Murphy will have it that it happens during night, in a storm and most crews today are trained to rely on the automation and rarely getting to hand fly, even less raw data, without any of the computers. The result will be another AF443 ...

    See the other links around, there's a Garmin manual showing the failure modes regarding loss of GPS data (even some people saying loss of GPS only should not cause YD failure) And it's AF447
