How do you think about to make this detail configurable?

Does the C programming language specify that integers are used as the default
data type (or if modifiers are used)?

Does the semantic patch language support to filter for omitted data types?

Would you like to distinguish the use case if this item was just forgotten or
intentionally omitted?
