To me it seems like a smart idea. Concentrate on a few chips so that
you can get the manufacturing yields up, the cost per component down,
and fewer parts to stock and manage from manufacturing all the way
through repair servicing. There are lots of overhead factors that
increase with the number of kinds of parts you have.
