Yes, it is removing a lot of things that were put in over the years to address certain problems, but the game has changed significantly since many of these changes were put in place which has made many of the changes no longer necessary or even some having the opposite effect than originally intended. Also, some of the changes were more like band-aids that tried to cover over a problem rather than addressing the underlying cause, and those often cause other problems.
So since there were so many little changes over so many years, and it is very hard to separate out the effects of each one, I felt what was needed was to rip everything out and go back to a simpler system designed with the above stated goals in mind. From there, as mentioned in the post, it should be easier to see what, if any, problems arise and it should be easier to pinpoint the cause and an appropriate way to handle them.
