I agree.

By the way, that issue has been already analyzed and seems solvable rather
easily, Doug is working on it with Richard' help.

Yes, you have a point. But now, since because of our "lazyness" we never
managed to attack the tree code limit, let's take this "crisis" as an occasion
to do that, or at least let's try to our best, instead of reverting completely
Doug' work, which is incredibly important for our implementation of C++0x
features and, I would say, gives GCC a great competitive advantage.
