THIS IS GREATER SECURITY?

Somewhat.

But . . . along comes the semi trailer/container . . .

A special panel opens and the rocket fires straight for the damn scant 100's of feet away.

Seems like something should be done to insure such did not happen.

Yes. The dam is still a target, but not as easy. The risk
is reduced to that of most non-road dams. Getting truck
bombs off the top is a major enhancement. Eliminating an
easy path to drop a bomb behind the dam is a major
enhancement.

... and does only cosmetic damage.

Dams are not that easy to bust with a frontal assault of
a weapon dropped, lobbed or rocketed at it. The Brits
found this out when they attacked German dams in WW-II.
They ended up designing special depth charges to air-drop
BEHIND the dam face.
