I think that Brooks' Second System Syndrome assumes that there is actually a compelling reason for the second system. A language is more subtle in that the value there is mostly in the convention of how to do things. In any case where you make a big change to a language there are always going to be people who either don't agree with the change or simply don't think the change is worth the bother. There are zillions of proposals for new languages around at any particular moment in time. Very few ever become popular. If you significantly change a currently popular language then there is a good chance that you will fall off the side into unpopularity.
