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

[cmeeren]

For a valid warning block, can any of the title or message properties under any circumstances (now or in the future) be null or omitted? Or are any of the aforementioned properties 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 the aforementioned properties 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! 😊

It would be really nice to make the title optional.

That would also allow to use the Warning block as a replacement/alternative for the Alert block: https://github.com/vishaltelangre/editorjs-alert
