My guess, based on the original stated goals of the project:
- Type-checking for all component data
Supporting compound product data types like structs would mean ECSx has to build or bring a much more involved Ecto-schema style solution for component structure definition, coercion, and validation.
Nothing I know about ECSx’s implementation or how ETS works suggests to me that this is impossible: but I’d imagine it’s not a priority for the framework devs.
