// Note on embedded protos: this is just for storing in a cache, so some formats
// were chosen ease of coding the initial implementation. In particular, where
// there already exists another serialization mechanism in Gerrit for
// serializing a particular field, we use that rather than defining a new proto
// type. This includes types that can be serialized to proto using
// ProtoConverters as well as NoteDb and indexed types that are serialized using
// JSON. We can always revisit this decision later; it just requires bumping the
// cache version.
//
// Note on nullability: there are a lot of nullable fields in ChangeNotesState
// and its dependencies. It's likely we could make some of them non-nullable,
// but each one of those would be a potentially significant amount of cleanup,
// and there's no guarantee we'd be able to eliminate all of them. (For a less
// complex class, it's likely the cleanup would be more feasible.)

// Instead, we just take the tedious yet simple approach of having a "has_foo"
// field for each nullable field "foo", indicating whether or not foo is null.
