Frans,
I've just started replacing my old entity fetching code with prefetch paths. Until recently, the old way of fetching related entities wasn't too burdensome because the relationships were simple. When I began working with an entity with more complicated relationships, I was frustrated because writing this code was so tedious and time consuming. Prefetch paths made my code so much simpler! Thanks for thinking of and adding this great feature before I needed it. Thanks for helping to make my coding more fun.
