Hash function adapted to work as bactracking resistant PRNG

Let’s consider PRNG which is updating its state by using some cryptographically secure hash function. So it takes some input, returns output and this output is a new input. And so on.

Of course there is a risk that such PRNG would fall into short cycle. But it can be resolved by combining the state with counter or Weyl sequence – then we can be sure it will achieve full period (the same as period of underlying Weyl sequence). According to proof in this paper:

This could quarantee also uniformity. Is this a good way to build bactracking resistant PRNG? Are there some dangers I do not see?
