Z/OS is modular to some degree. There is the core OS and some add-on
software which is almost necessary and utilitarian. After that are
additional products to configure the OS to a customer's requirements. Then
add on the application software which further individualizes the system for
the company.
Also the license stays with the company, not the machine. And backward
compatibility is usually not an issue.
Z/OS probably needs more disk storage than Windows to hold all its
components, but at least it has a mechanism to identify the different parts
and allow us to configure the OS to include or exclude these parts in the
running configuration.
