Adding new modded blocks is not a trivial or purely config-driven task.

At the moment, custom blocks can only be added if you are willing to supply
all required data assets yourself (a preset/template may be provided).

This includes, but is not limited to:

• Item and block model JSONs
• Blockstate JSONs
• Loot tables, recipes, and tags
• Advancement JSONs
• Language entries

If all of these assets are provided correctly and follow the expected
structure, it is technically possible to add custom modded blocks.
However, this is closer to authoring a datapack/resource pack extension
than a simple configuration change.
