I fear my colleagues responsible to maintain the productive versions
would not be happy:
They want the system to be as stable as possible.
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.
