SRB is one method to execute authorized code in any address space but surely
you must be familiar with others such as SVC, PC and IEFSSREQ. Or are you
suggesting that getmain and storage macro's somehow use an SRB to execute
authorized code in any address space?

What do you mean by that? A PC instruction can pass control to code
in a specific address space, as defined when the PC routine was
established. What you describe as being able to run code in any
address space sounds more like scheduling an SRB.
