No, is the simple answer.

Not all of them have flakey fibres. Some of them have been trouble-free. Quite a chance of having issues though.

The CITES changes means that proper rosewood boards should be the norm again, so there’s no need to pick an engineered board. In some instances it may be that the kit description hasn’t been fully updated. I’ve seen one current one for the DMS-1 where the description offers maple or rosewood boards and the body material has changed to mahogany, not ash as the picture shows, but the options tick list still lists blackwood, not rosewood.

You’d really have to email PBG for confirmation.
