It's a bit of a shame that radiation hardened chips are stuck so far in the past.

I believe the volume is so low it does not warrant the investment to make radiation hardened versions more often.

Actually being stuck in the past might be a feature. Denser circuitry is likely to be more vulnerable to interference by ionising radiation and more vulnerable to physical damage from high energy particles.

Parts of hardening include enlarging physical features and increasing operating voltage
