Admittedly it's been a while since I've refreshed on my anti-tank skills, but we were always taught that HEAT rounds deal with concrete pretty effectively. For example, I believe the APILAS with an RHA penetration of around 650 - 700 mm was told to penetrate around two meters of concrete. So I'd say penetration is of no problem.

However I must agree on your second point. The after armor effects would probably be considerably less catastrophic than in a tank. With less tightly packed stuff ready to explode, probably not as cramped as a tank and like you said with less molten steel spraying around, I'd imagine that bunker would survive a penetration much better than a tank.

I'm not sure if fortifications are already coded that way, but I'd imagine that it would better reflect reality if direct hits at bunkers would more often just take out a weapon slot or two rather than outright blowing up the entire thing. But that's might be just me.
