editor-js
Output format: Which properties (if any) can be null omitted?
For a valid table block, can the content property under any circumstances (now or in the future) be null or omitted, and can any array element in content (either the top-level array items representing the rows, or the second-level string content values) be null? Or are they 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.)
