No, it's always been this way. As long as the target drive can accommodate the space required for the stripe, you're OK. Certain vendors have restricted rebuild operations to matched drives for safety and performance reasons. Some still do.
It's really only partly a function of the hardware, and then the rest is the controller coordinating the RIS sector on the drives. As long as there is a place for the RIS sector, and the data contained in the stripe it will work.
