That’s a credible idea. Similar to CIWS but using the larger HE shells AAA offers. If I had to guess I’d say there are limitations of accurately setting the warhead’s fuse along with the high CEP of inertial targeting for a ballistic target interception.
Slight variances in AAA muzzle velocity may also pose issues for successful interception.
A missile otoh can make the necessary in-flight adjustments to its launch solution for greater likelyhood of interception.
Similarly, spamming HE CEWS would likely incur higher collateral damage.

I agree there are a number of AAA targeting variables but I tend to believe CEP related issues can be overcome through barrage fire. The rockets themselves have very predictable trajectories. It seems to me that multiple guns under central control could barrage fire automatically fuzed projectiles and achieve a sufficiently dense bracketing to bring the rocket down.

True and that's why systems like Iron Dome would be the second line of defense should the less expensive AAA fail to bring down the rocket. Obviously, the entire system would require integrated targeting and fire control.

Fuzing would result in shrapnel and hopefully pieces of rockets returning to earth. Air defense sirens would have been wailing so, people would have been alerted to take shelter.
