Don't we need mapping here?

This assist generates entirely new code (a new impl block) rather than editing existing syntax. Mappings are needed when using SourceChangeBuilder::make_editor() to edit existing syntax trees, where we need to track the relationship between original and new nodes for features like snippet placeholders. Since we're doing pure code generation, the mapping overhead is unnecessary.
Here is my understanding, is that right?
