Thank you, Master!  Shall I fetch the Rolls with the concubines?  ;^)

But seriously, you ask a very good question, and given that a) I've
personally fried way too many 2164s by powering them backwards, and b) we're
just about to unleash a whole bunch of 2164-based modules on the Eurorack
market (basically, a buncha guys who like to twiddle their little knobs), I
think a bit of circuit protection is a no-brainer.
