While they may not be entirely unhelpful and avoiding the question of dubious authenticity, at what point do beer styles become so diversified as to be useless? Originally envisaged in a different and hierarchical structure, they have become a mile wide and an inch deep. They have become so finely sliced that you can almost trigger the identification of a new style by brewing a new popular beer. I recommend fern beer be the next. Hardly a satisfying taxonomy.
So, who shall be the Einstein to get us out of the Newtonian construct?
