I believe that a major purpose of this thread is to help newer players find out what is good and not good to use on a team without doing extensive research on each Pokemon (usage statistics which determine which Pokemon are OU do not help with that). Most of us more experienced players are well aware of each individual Pokemon's strengths and weaknesses which matter more to us than the letter grade. If a newer player sees Charizard, Pinsir, and Venusaur all in the S rank, it will probably take him a little while to figure out that he cannot use all three on the same team since they all need their mega forms. Yes, there are more Pokemon to rank, but ranking megas separately minimizes the confusion which would otherwise exist if we just lumped both (or all three in the case of Charizard) together.I'm also more of the opinion that we should just group up Mega Evolutions with their base form. It lowers the amount of pokemon to rank. Let's have some faith in the smogon community that when they see Charizard as S rank they don't immediately run base Charizard.
