Output format: Which properties (if any) can be null omitted?

[cmeeren]

For a valid checklist block, under any circumstances (now or in the future) :

• Can the items property be null or omitted?
• Can any array element in items be null?
• Can the text or checked properties of any item be null or omitted?

Or are all of the aforementioned properties/values guaranteed to always be present and non-null for this block to be valid?

Context: I'm a back-end .NET developer needing to parse Editor.js documents. The readme lists all of the aforementioned properties/values but does not explicitly guarantee that they will always be present and non-null. Back-end deserialization/parsing in strongly typed languages would be easier with some guarantees about which properties can and can not be null/omitted. (Ideally, any such guarantees should be added to the readme to ensure they are formalized and kept in the future.)

Could anyone clarify this, please? Thanks! 😊
