But as a deterrent, you would need this to be reasonably accurate, yes?

  Why? All you really care is whether the boom is big enough, and that you can deliver it on target. The latter was a big reason for optimising bomb construction, but you can just as well optimise your launchers - which leads to missiles like R-36, where the main difference between it and a space launcher is replacing the payload. Yes, early USA ICBMs also serve as base for space launches, but unlike R-36 were much less storable (except for Titan, iirc) and less powerful.

  If we're talking about devices with megaton or hundred-kiloton yields, accuracy isn't super important. And simpler, unminiaturized weapons are probably going to be bomber-dropped anyway.
