Speaking from the Mesa side, I think part of our problem is that it's
not easy to build the entire mesa tree, which means that the developer
doing the merge cannot even compile-test the result, meaning that many
trivial failures go unnoticed.

I'd argue that if we had a maximal mesa build target that compiled
*everything*, regardless of whether it produced drivers or not, we'd
have a much better chance of catching bogus merge droppings.

Despite Jose's valid concerns, I'd still argue that the situation we
have now is superior to what came before - where people were supposed to
be cherry-picking bugfixes but more likely they were forgotten or it
fell on Brian's shoulders to do manually.
