You could keep the bipolar from saturating with a Schottky clamp, but
at the expense of even more parts.
Don't single packages containing transistor and clamp exist?
They do. I've been trying to stick to more "standard" devices
(for some nominal definition of "standard") to minimize
both overall cost and the probability of early obsolescence. I
haven't done enough research into integrated Schottky
transistors to see if there are any which approach 2N3904/4401
levels of popularity, but that's all in my queue.
