Why use a contractile or saxon saga for sampling?

Question

I continue to read that for handling side effects I have to use the reduction-thunk or redux saga. Why not just use action creators to submit multiple actions:

function loadProductActionCreator(dispatch) {
  dispatch({
    type: 'load_product',
  })
  fetch('api/product').then(
    function (r) {
      return r.json();
    }
  )
  .then(function (res) {
    dispatch({
      type: 'loaded_product',
      data: res
    })
  })
}

I tried this and it worked ( full code ). Therefore, I suggest that there should be some inconvenience that I do not know about.
