Twice in 8 days a mail or calendar call hung until the session hit its idle timeout and quit. The morning stack cannot depend on a call that might sit there for half an hour. I still need the messages. I do not need them on the path that has to finish.
I planned the hardening and approved the plan. The calls that hang move off that path, and the morning uses the short tool that already knows how to read the same mail. It was not built before the week ended. The failure mode is written down, which is what I can use the next morning if it hangs again.
