With 20:20 hindsight, I can speculate about the fact that

have happened long before now.  Of course who knew that
the 5071 would still be in production 30 years after
this decision was made?


and the "market lifetime" of parts today is much shorter. There are lots of parts from Hittite that were essentially "run on this line only", and when they moved geometries, they're never to be seen again.

5 years is a good run these days.
