Right, so you're thinking of tasks rather than calendars. So we can look at making some things optional in JMAP tasks: I agree that the ability to assign participants may be reasonable to make optional there. But it's important to keep the options as few as possible, as otherwise the implementations become so different that it becomes very hard to build a good client that can handle all of them, so you miss out on the whole point of an open standard: interoperability.
