Coastal Guns-only benefit from Artillery tech not Naval Weapons?

[Elessar2]

Is this working as designed? Their entire raison de etre was to sink ships, not lob shells onto land targets. The ur-example there would have to be the guns of Singapore, which were not equipped with HE, only AP. Wouldn't it make more sense to allow them the two levels of Naval Weapons, perhaps starting with ship attack ratings of 1 not 2 (so the progression would be 1-2-3)?

I'm kind of curious why no one has weighed in on this.

I'm uncertain what my comment might be, though. And maybe I'm not alone in that. But would definitely appreciate hearing the perspective of others.
