It's likely that this will be the first time a piece of space hardware unintentionally strikes the Moon. Typically, during interplanetary missions, a rocket's upper stage is sent into a heliocentric orbit, keeping it away from the Earth and its Moon.

For launches of spacecraft intended to orbit the Earth, the best practice is to reserve enough fuel in a rocket's upper stage to return it to Earth's atmosphere, where it will burn up. This is what SpaceX and most Western rocket companies customarily do to help control debris in low Earth orbit. The Moon, of course, has no atmosphere for the stage to burn up in.

(The “minimize human disturbance of Moon” bit was indeed my personal thought and not really from either article. To me it’s akin to crashing and abandoning a vehicle in a national park: the park will survive just fine but it’s something we should try to avoid if possible.)
