I think you are making this sound a little bit too easy.
4NT is a rather strong suggestion about strain, and it could easily be an unacceptable bid, if for instance one of our black suits is too weak.
So we need a punt quite often here. If we are punting 3♥ with anything (even a small singleton), we might just as well define it as artificial - saying nothing about hearts.
On the theoretical side, it seems wrong to me to have TWO ways to support diamonds in this inelegant auction, while all cumbersome hands + hands that actually want to suggest hearts have to go through 3♥. This approach begs for troubles later.
