no, that's exactly the thing that does *not* work for qt. the computing
capacity required to support that model (with the primitive tools we're
apparently capable of utilizing) would be *enormous*.

(of course, one can argue that all the pointlessly failed integrations
effectively thwart the advantage of batch integrations. somebody would
have to do the math to make an actual judgment call.)

another reason why this model may not work too well is qt's abysmal test
coverage in many areas. as annoying as the current system is, it *does*
prevent non-obvious, indirect breakages from going in from time to time,
because people can't just deny responsibility past a certain point.
