SQLiteData & CKSharing - Many-to-Many under a single Root record

[MrSkwiggs]

I'm trying to wrap my head around CKSharing, and while I understand the reasoning for not supporting many-to-many as explained in the docs, I'm wondering why I could not simply make all components of a M2M relation "nested" under the root record?

If we take the Reminder example, why could I not tie Tags to ReminderList? then it would be very clear that a set of tags only exists for a given list, right? Meaning it'd be clear what happens if a tag is deleted/edited (it would only affect the Reminders nested in that list, which are shared themselves).

I feel like this being such a clear-cut use case, it doesn't make sense that it would not be supported at the CloudKit level even... 🤔
