I am definitely not clued in enough to have a strong opinion on this. But from looking at the situation from some distance, it seems the basic issue is that often one must use a version of gcc that's new enough, because of some feature used in the code and sometimes one must use a version that's old enough because something breaks with the latest. That seems to be more true of gcc than clang. It would help if we had better version selection logic, and then maybe we could start pruning. I don't see any way to predict that we can update 5.1 to 5.2 without keeping 5.1. Past history doesn't make that seem likely.
