If they need to introduce a new component, they usually prefer to just add this one component. Only if this forces other updates, they reluctantly will make them. The motivation for this behaviour: even if a newer version is supposed to be backward compatible, it often has slightly different behaviour which may trigger bugs in the other parts of a complex system.
That's why one should have enough tests...although tests will never cover all cases. -aj
